Ответ:

5 км

Объяснение:

Дано:

V₁ = 180 км/ч = 50 м/с

V₂ = 37,5 м/с

t = 1 мин 20 с = 80 с

_____________

S - ?

По теореме Пифагора:

V = √ (V₁² + V₂²) = √ (50²+37,5²) ≈ 62,5 м/с

Модуль перемещения:

S = V*t = 62,5*80 = 5 000 м или 5 км

How To Plan Your Life To Have Free Time Every Day

We all need some free time to perform better afterwards and grab the opportunity to do the things that we like and we cannot always do. There are often not enough hours in our days to complete our pending tasks, let alone to enjoy our leisure time. Learning how to plan your life today.

The key to achieving this is to properly plan it. If you can establish habits in your daily routine to organize your day, you will have free time to enjoy your favorite pastimes. Follow these guidelines to make it happen:

Create a timetable

One of the keys to taking action is to elaborate a to-do list. In addition to writing down everything you want to do, set a timetable for it. Set your rhythm, estimate approximately how long it will take you to do this or that and set a specific time. Think about the time that may be more appropriate for each task (we are usually more productive earlier in the day than at the end of it).

Be flexible

Your timetable need not be inflexible. During the day, pressing issues will come up that will need your whole attention, but remember that not everything which seems urgent really is. Your plan is not set in stone; assume that it can be changed, just try to consider the unexpected in order to meet your schedule.

Week by week

The best planning of your life are usually those for the week. It is important to think about what you are doing tomorrow to organize properly today. Every day, our tasks are similar, so making a weekly plan will turn out to be easy and you will carry out many more tasks than you would if you thought only day by day.

Plan your free time

Since you have already managed to organize your tasks, it is now time to plan your leisure time. Your hobbies can also be well structured to maximize your personal time. Do not get obsessed with organizing everything to the millimeter, but the clearer it is in your mind what you want to do, the better you will enjoy your weekend or your holiday’s time.

Your free time is important, just as much as your work. Do not get carried away by the turmoil and the stress; take leisure seriously and use it to recharge your batteries and reduce your stress level. Enjoying our hobbies and spending time with our people has positive results in our mood.

Think about what you would like to do

Do not waste your free time on unproductive things; do not let resting time catch you unprepared, not knowing what to do or not doing “anything”. Think in advance how to fill those spaces for you, use that time to do something that you like, take it as a prize for the work done.

Today vs Tomorrow

Put your plan into practice today; do not wait until tomorrow to turn it into a habit. At first it will require you to make a good effort, but then it will become a habit that you will routinely repeat. Before you know it, you will have created a solid routine that will earn you free time every day.
