ДОМАШНЕЕ ЗАДАНИЕ 9 Выполни задание. Расстояние между двумя лыжниками, одновременно начавшими движение в одном направлений по ровной заснеженной сте- пи - 700 м. Скорость идущего позади лыжника - 200 м/мин. Через какое время Он догонит Идуще- го впереди со ско- ростью 150 м/мин? решать уровнением ПОМОГИТЕ ПОЖАЛУЙСТА ДАЮ 20 БАЛЛОВ!!!!!!!!!!​

Answer 1

Ответ:

1) 200 м/ мин - 150 м/ мин = 50 м/ мин скорость отдаления.

2) 700 м : 50 м/ мин = 14 мин через такое время догонит

Answer 2

Solving the Problem of Overtaking in Skiing

To solve this problem, we can use the concept of relative speed. The relative speed of the overtaking skier with respect to the skier ahead is the difference between their speeds.

Given: - Distance between the two skiers, d = 700 m - Speed of the skier behind, v1 = 200 m/min - Speed of the skier ahead, v2 = 150 m/min

Calculating the Time of Overtaking

The time it takes for the skier behind to overtake the skier ahead can be calculated using the formula: Time = Distance / Relative Speed

The relative speed is the difference between the speeds of the two skiers.

Relative Speed = Speed of skier behind - Speed of skier ahead

Let's calculate the relative speed and then use it to find the time it takes for the skier behind to overtake the skier ahead.

Calculation

Relative Speed = 200 m/min - 150 m/min = 50 m/min

Now, we can use the formula: Time = Distance / Relative Speed

Time = 700 m / 50 m/min

Time = 14 minutes

So, the skier behind will overtake the skier ahead in 14 minutes.

I hope this helps! If you have any further questions, feel free to ask.
