Question

С провотиположных сторон лыжной трассы одновременно навстречу друг другу вышли два лыжника.Расстояние между ними было 5250м,и лыжники встретились через 15 мин.С какой скоростью шел второй лыжник,если скорость первого лыжника была 180м/мин

Answer 1

1)180*15=2700(м)- прошел 1 лыжник за 15 минут 2)5250-2700=2550(м)-прошел 2 лыжник за 15 мин 3) 2550÷15=170(м/мин)

Answer 2

Problem Analysis

Two skiers are skiing towards each other on a ski slope. The distance between them is 5250 meters, and they meet after 15 minutes. We need to find the speed at which the second skier is skiing, given that the speed of the first skier is 180 meters per minute.

Solution

To solve this problem, we can use the formula: speed = distance / time.

Let's calculate the speed of the second skier using this formula.

Calculation

The distance between the skiers is 5250 meters, and they meet after 15 minutes.

Using the formula speed = distance / time, we can calculate the speed of the second skier as follows:

Speed of the second skier = Distance / Time = 5250 meters / 15 minutes

Calculating this, we find:

Speed of the second skier = 350 meters per minute

Therefore, the second skier is skiing at a speed of 350 meters per minute.

Answer

The second skier is skiing at a speed of 350 meters per minute.
