Know the time and distance, how to find the speed. How to find time for what matters most

In the given task we are asked to explain how to find the speed, time and distance in the problem. Problems with such quantities are classified as motion problems.

Movement tasks

In total, three basic quantities are used in motion problems, as a rule, one of which is unknown and must be found. This can be done using formulas:

  • Speed. In the problem, speed is a quantity that indicates how far an object has traveled in units of time. Therefore, it is found by the formula:

speed = distance / time.

  • Time. In the problem, time is a quantity that shows how much time an object spent on a path at a certain speed. Accordingly, it is found by the formula:

time = distance / speed.

  • Distance. Distance or path in a problem is a quantity that shows how far a subject has covered at a certain speed over a certain period of time. Thus, it is found by the formula:

distance = speed * time.

Bottom line

Thus, to summarize. Movement problems can be solved using the above formulas. Tasks may also contain several moving objects or several segments of path and time. In this case, the solution will consist of several segments, which are ultimately added or subtracted depending on the conditions.

In this lesson we will look at three physical quantities, namely distance, speed and time.

Lesson content

Distance

We have already studied distance in the lesson. In simple terms, distance is the length from one point to another. (Example: the distance from home to school is 2 kilometers). When dealing with long distances, they will mostly be measured in meters and kilometers. The distance is indicated by a Latin letter S. In principle, it can be designated by another letter, but the letter S generally accepted.

Speed

Speed ​​is the distance traveled by a body per unit time. A unit of time means 1 hour, 1 minute or 1 second.

Let's assume that two schoolchildren decide to see who can run from the yard to the sports ground the fastest. The distance from the yard to the sports ground is 100 meters. The first student ran in 25 seconds. Second in 50 seconds. Who ran faster?

The one who ran the longest distance in 1 second ran faster. They say that he has greater movement speed. In this case, the speed of schoolchildren is the distance they cover in 1 second.

To find the speed, you need to divide the distance by the time of movement. Let's find the speed of the first student. To do this, divide 100 meters by the time the first student moves, that is, by 25 seconds:

100 m: 25 s = 4

If the distance is given in meters and the time of movement is in seconds, then the speed is measured in meters per second (m/s). If the distance is given in kilometers and the travel time is in hours, the speed is measured in kilometers per hour (km/h).

Our distance is given in meters and time in seconds. This means speed is measured in meters per second (m/s)

100m: 25s = 4 (m/s)

So, the speed of the first student is 4 meters per second (m/s).

Now let’s find the speed of movement of the second student. To do this, divide the distance by the time the second student moves, that is, by 50 seconds:

100 m: 50 s = 2 (m/s)

This means that the speed of the second student is 2 meters per second (m/s).

The speed of movement of the first student is 4 (m/s)

The speed of movement of the second student is 2 (m/s)

4 (m/s) > 2 (m/s)

The speed of the first student is greater. This means he reached the sports ground faster. Speed ​​is indicated by a Latin letter v.

Time

Sometimes a situation arises when you need to find out how long it will take a body to cover a particular distance.

For example, from home to the sports section is 1000 meters. We have to get there by bike. Our speed will be 500 meters per minute (500m/min). How long will it take us to get to the sports section?

If we travel 500 meters in one minute, then how many such minutes with five hundred meters will there be in 1000 meters? Obviously, we need to divide 1000 meters by the distance that we will travel in one minute, that is, by 500 meters. Then we will get the time it takes us to get to the sports section:

1000: 500 = 2 (min)

Movement time is indicated by a small Latin letter t.

Relationship between speed, time, distance

Speed ​​is usually denoted by a small Latin letter v, time of movement - by a small letter t, distance traveled - small letter s. Speed, time and distance are related.

If the speed and time of movement are known, then the distance can be found. It is equal to speed multiplied by time:

s = v×t

For example, we left the house and headed to the store. We reached the store in 10 minutes. Our speed was 50 meters per minute. Knowing our speed and time, we can find the distance.

If we walked 50 meters in one minute, then how many fifty meters will we walk in 10 minutes? Obviously, by multiplying 50 meters by 10, we determine the distance from the house to the store.

v = 50 (m/min)

t = 10 minutes

s = v × t = 50 × 10 = 500 (meters to the store)

If time and distance are known, then you can find the speed:

v=s:t

For example, the distance from home to school is 900 meters. The student reached this school in 10 minutes. What was his speed?

The student's speed is the distance he travels in one minute. If he covered 900 meters in 10 minutes, how much distance did he cover in one minute?

To answer this, you need to divide the distance by the time the student moves:

s = 900 meters

t = 10 minutes

v = s: t = 900: 10 = 90 (m/min)

If the speed and distance are known, then you can find the time:

t = s: v

For example, from home to the sports section is 500 meters. We must reach it on foot. Our speed will be 100 meters per minute (100 m/min). How long will it take us to get to the sports section?

If we walk 100 meters in one minute, then how many such minutes with a hundred meters will there be in 500 meters?

To answer this question, we need to divide 500 meters by the distance that we will cover in one minute, that is, by 100. Then we will get the time it will take us to get to the sports section:

s = 500 meters

v = 100 (m/min)

t = s: v = 500: 100 = 5 (minutes before the sports section)

Reluctantly waking up to an alarm clock, frantically getting ready for work, a dry breakfast on the run, traffic jams on the way to work, rush hour in the office and more traffic jams, eternal rush, city bustle, annoying weather and gloomy passers-by, a constant state of lack of sleep and fatigue, lack of time and energy , headaches... Have you long forgotten when you smiled just like that, rejoiced at the starry sky, sang in the shower or danced in the rain... Sound familiar, do you recognize yourself?

No time, no money, no opportunities, I can’t afford it - how often do you justify to yourself that you can’t start a new life on the next Monday?

How to find time for yourself in the rhythm of a big city, and why you need it - says hatha yoga and fitness instructor Victoria Mozhina.

When we are constantly in the whirlpool of things to do, we simply don’t have time to think. We run unknown where and why, without even thinking about life goals, about our true desires and dreams. Every day, hour after hour, we deplete our internal mental, emotional, energetic and physical resources, enter a state of semi-conscious automatism, stop noticing life and its beauty, and become victims of stress, illness and depression.

When we are filled and calm, then most of life's problems, difficulties and unpleasant situations are resolved with ease. We receive in response from the world around us exactly what we transmit to it from our state. Therefore, it is fundamentally important to create your own mood and fill yourself with pleasant emotions and energies, which can later be shared - with friends, relatives, colleagues and even random passers-by.

Our brain filters information coming from the world around us, perceiving only what is synchronous with its state. That’s why it’s so important to tune your filter to a wave of calm and high resource state. This kind of adjustment cannot be done in the rhythm of the daily mad rush - for this it is extremely necessary to devote time to yourself.

Even yoga instructors have a rule - the time of personal practice (practice for yourself) should be no less than the time spent with students as a teacher. Otherwise, resource depletion and rapid professional burnout occur. This applies to each of us, in any area of ​​our lives - in work, family, friendship. To share, to give, we must fill ourselves, draw energy, replenish our resource state. Haste and routine drain resources and block creative flow.

Once, during a period when I was actively engaged in business, a crisis came, the ruble exchange rate collapsed, one after another suppliers began to close, sales fell, and the bankruptcy of the company loomed on the horizon - I, already thoroughly exhausted by the crazy pace of life, reduced immunity, lack of sleep and chronic stress, I just couldn’t think of anything better than... to fly away on vacation to Bali.

Just two weeks of morning surfing and evening yoga on the coast gave me such a powerful charge that upon returning, all the problems and difficulties were resolved in a matter of days. And all because the rested brain began to generate creative ideas with incredible efficiency!

Since then, when faced with any “unsolvable” problem, the first thing I do is switch from mental work and allocate time for conscious work with the body (hatha yoga, Thai boxing, swimming, jogging in the fresh air, sauna ), or I don’t do anything at all, I don’t answer calls and messages, I don’t go to the computer, I don’t communicate about work issues. I jokingly call this “time to look down.” Just a few hours of such unity with yourself restores no worse than a week of vacation.

My lifehacks for resource recovery:

  1. Do yoga. Hatha yoga is one of the most powerful, proven and reliable ways to restore and strengthen the connection between the body, mind and emotions, between yourself and the world. By controlling attention through breathing, movement, gaze and bandhas (internal locks), we master concentration and deconcentration techniques, clear our perception of reality and increase daily awareness, as well as improve health and stabilize our mental state.
  2. Start small. Set aside at least 15 minutes twice a day for yoga, meditation, reading books or doing nothing (this is quite a bit, we spend much more time looking at social networks), and an hour at least twice a week.
  3. Start a diary (task planner), even if you are a housewife. And every evening, plan your tasks for the next day. Plan both work and free time. In writing, it will be easier for you to highlight the main tasks, as well as postpone or completely eliminate the secondary ones.
  4. Delegate repetitive, routine tasks and highlight those things that someone else besides you can do. Feel free to give them to others, ask for help. The freed up time is yours (and you don’t need to fill it with new things)!
  5. Combine. Everyone's ability to multitask is different. But there are things you can definitely do together. For example, riding in a car (bus, subway) and listening to an audiobook that you don’t have time to read in paper form. While your car is at the wash, leave your phone number with the staff and take a walk.
  6. Learn to plan your routes correctly, so that you can combine useful things with small joys. For example, going shopping and doing yoga at a nearby studio, or going to the beach at sunset. Sounds tempting, doesn't it?
  7. Follow the regime. Leave work on time (if you have regular working hours, you have the right!). Take breaks to concentrate better. Go to bed on time. Remember that it is better to go to bed before midnight. At this time, sleep intensity is much greater, and immunity is restored. Better get up earlier in the morning and do things that you didn’t have time to do in the evening.
  8. Use the morning for yourself. If you learn to get up at least a little earlier than usual, you can successfully use the precious morning hours for yourself. Some activities are best done when everyone is still asleep and simply cannot disturb you. No one will stop you from going about your business. Even the phone doesn't ring at these hours. You can easily do your morning yoga practice without embarrassing your household. Think about what else you can do in the morning before breakfast and waking up your loved ones.
  9. Learn to say "NO" to anyone and everyone who tries to take your personal time. No to chatty clients, no to boring consultants, no to colleagues dumping their work on you, no to advertising on TV, no to the TV itself, and also to everyone who sits on your neck! You will never be able to find extra time for yourself if you do not protect it from encroachments.
  10. Have regular digital detox days– turn off gadgets, do not open your laptop, do not read news and social media. networks. Put aside your “digital habits” for a while, communicate with loved ones and indulge yourself in the activities that you truly enjoy. This will energize you and you will later return to your work more focused.
  11. Think about your “global” life goals and dreams. Write them down. The chosen direction in life will allow you to easily cut off unnecessary things, unnecessary communication and stop wasting time on unimportant matters.
  12. Create a daily ritual. For example, if you have a very large family or small children, then you can get up half an hour earlier, brew a cup of aromatic tea or invigorating pu-erh, and just with foam, listening to your favorite music, evening meditation, morning yogic practice “surya namaskar”. The main thing is that this action is pleasant for you, and you can enjoy the morning silence until the moment when your household wakes up. Over time, this can become your pleasant ritual. Instead of bemoaning the constant lack of personal time, simply build it into your daily schedule. After all, it's not that difficult. Gradually, this approach will become a habit, and you will notice how much happier and healthier you become.

Don't lose yourself in this hectic world, friends! Don’t lose touch with the world and yourself, because we have only one life. And I wish you to live it as consciously and fully as possible!

We live in an era where we are constantly distracted. Therefore, we need to be especially careful about how we distribute our time.

First, calculate how much time you spend each day on a particular activity. Then multiply this number by seven - how many hours you will spend on this in a week. Calculate how much time it takes you to do everything you do and add up the results. And then subtract that amount from your total hours per week (168).

It will look something like this:

  1. Internet and television: ____ × 7 = ____ (per week).
  2. Work or study: ____.
  3. Chat with friends: ____.
  4. Time with family: ____.
  5. Sports: ____.
  6. Reading for pleasure: ____.
  7. Dream: ____.
  8. Cooking and eating food: ____.
  9. Travel time: ____.
  10. Other: ____.

Total: ____.

168 – ____ (sum of hours worked per week) = ____.

This will give you a general idea of ​​how you manage your time. You may be able to discover some free hours that you didn't know you had.

Now determine how much time you are wasting uselessly. Be honest with yourself: what activities really benefit you, and what just clogs up your day? Review your list carefully. It may well be that you spend five hours a day on Facebook, YouTube, etc.

The StayFocusd browser extension will help you overcome this habit. It allows you to limit the time you spend on a particular site that is currently taking up too much of your time.

How to find extra time

Choose your bedtime wisely and get up earlier

Remember how often it happened that even after 11 hours of sleep you felt sleepy and tired. Or, on the contrary, having slept for only three hours, they were full of energy. This has to do with our sleep cycles. Each cycle lasts 90 minutes, so it’s best to sleep for one and a half, three, four and a half, six hours and so on. Try to determine for yourself the right time when it is most comfortable for you to go to bed and get up.

How to make the most of your time

1. Set yourself goals

When we don't have specific goals, it's very easy to "accidentally" waste time on unnecessary activities. And when we know what we are striving for, it is easier for us to devote our attention to it and not be distracted.

Set yourself 3-5 main goals for the year ahead in each area of ​​life (work, health, relationships, self-development, travel). Be very specific about your goals and write them down in the present tense, as if you have already achieved them. For example: “I speak English (Italian, Chinese) fluently.” All you need to do is write down your goals and take action.

2. Identify the most beneficial activities to achieve your goals.

You can apply the well-known Pareto law (80/20 rule). According to this law, 20% of your efforts produce 80% of your results. Identify the three most important tasks that are most helpful to achieving your goals and spend the most time on them.

3. Develop your morning ritual

The right morning ritual will help you start your day effectively. Include in your ritual those activities that will help you move towards your goal. For example, if you want to start your own blog, you need at least one article per week. Set aside 30-60 minutes in the morning to write.

Here are some more helpful tips for an effective morning ritual:

  • Drink water. Your body hasn't received water all night, it's time to restore your water balance.
  • Win a small victory - do something you can be proud of.
  • Play sports. Any type of physical activity is suitable: yoga, walking, running, swimming.

4. Automate, delegate and eliminate unimportant tasks

We usually think that we have to do everything ourselves. However, it is not. Think about what you were going to do today and look for less important tasks. From them, choose what can be automated, delegated to someone else, or completely eliminated.

5. Schedule a meeting with yourself

If you constantly have to communicate with a lot of people at work, be sure to schedule a time when you can completely focus on your own tasks. During the working day, you may have two or three meetings with yourself.

6. Work intermittently

The well-known “”, developed in the late 1980s as a time management tool, is perfect for this. This approach involves breaking your work into 25-minute intervals and then taking a five-minute break. This not only increases productivity, but also helps you avoid overwork.

7. Rest

After doing a lot of work, our energy levels tend to drop. In such a situation, try to find a quiet corner in the office where you can sit with your eyes closed. It is not necessary to sleep, the main thing is for the body to relax.

8. Always plan ahead

If you have an important meeting or other event coming up, be sure to leave some extra time in case something goes wrong.

For example, if your meeting is scheduled for 3:00 p.m., arrive by 2:45 p.m. Just in case. Also, set your own deadline for a project a few days before the official deadline.

9. If something doesn't go according to plan, don't be upset.

Even if you are a master of productivity and time management, unexpected delays still await you, because very often we depend on external circumstances. If you're sitting in line or waiting for a late colleague, spend that time reading or an interesting podcast. And don't be upset.

10. Keep track of what you spend your time on and evaluate the results.

Note how much time you spend on important activities, and evaluate the results at the end of the week. Take 30 minutes to reflect on what was productive and what was not. This will help you notice the reasons for wasting time.

11. Make time for household chores

Dedicate one day a week to cleaning, grocery shopping, and other household chores so that you don’t waste time on this on other days.

12. Say no to meetings

If meetings do not have a specific purpose, then they are meaningless. On average, there may be three to four meetings per day, each lasting 30–60 minutes. Ask what the purpose of the meeting you are being invited to is and decline if it is completely unrelated to your business. Of course, this is not always possible, but if you can do it, you will save time on more important tasks.

13. Say no to email

No email until you've finished your morning routine. And generally, don't check your email more than twice a day. If someone needs you, they will find you.

14. Say “no” to things that don’t align with your goals.

Along with tracking your progress, the main thing that will help you not deviate from the established schedule is. Remember, this doesn't mean you're saying no to others, you're saying yes to yourself.

15. Reward yourself

You don't have to write down your whole life minute by minute. At the end of a productive work week, treat yourself to a whole day or at least a couple of hours of rest.

16. Develop an evening ritual

At the end of the day, remember what important, good and interesting things happened today. Benjamin Franklin, for example, always asked himself: “What good have I done today?”

17. Take a break from technology

An hour before bedtime, turn off your computer, phone and all other gadgets. Better spend time with loved ones or read.

Let's sum it up

It can take years to develop the habit of managing your time well. Remember that you don’t have to strive for perfection. In this case, consistency is much more important. Choose the methods that suit you and take action!
