ДОМАШНЕЕ ЗАДАНИЕ 9 Выполни задание. Расстояние между двумя лыжниками, одновременно начавшими движение в одном направлении 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​

Answer 1

Ответ:

200-150=50(м мин)

700:50=14(мин)

Пошаговое объяснение:

Догонит через 14 мин.

Answer 2

To find the time it takes for the skier behind to catch up to the skier ahead, we can use the formula:

Time = Distance / Relative Speed

In this case, the distance between the two skiers is 700 meters, and the relative speed of the skier behind (200 m/min) is the difference between the speed of the skier ahead (150 m/min) and the speed of the skier behind.

Let's calculate the time it takes for the skier behind to catch up to the skier ahead:

Calculation:

Distance = 700 meters Relative Speed = Speed of the skier ahead - Speed of the skier behind = 150 m/min - 200 m/min = -50 m/min (negative because the skier behind is slower)

Time = Distance / Relative Speed = 700 meters / (-50 m/min)

To find the time, we need to convert the relative speed to a positive value. So, we'll take the absolute value of the relative speed:

Time = 700 meters / (50 m/min)

Now, let's calculate the time:

Time = 14 minutes

Therefore, the skier behind will catch up to the skier ahead in 14 minutes.

Please note that the calculations are based on the given information and assumptions.
