Question

Задача нужны действия. Из 2ух полярных стоянок, расстояние между которыми 76 км, одновременно в противаоположные стороны направились снегоход и лыжник. Скорость снегохода 13 км в час, а скорость лыжника 6 км в час. какое расстояние будет между снегохода и лыжника через 2 часа?

Answer 1

76-(13+6)*2=76-19*2=76-38=38км будет между ними через 2 часа

Answer 2

Problem Analysis

We are given two polar stations that are 76 km apart. A snowmobile and a skier start simultaneously from these stations and move in opposite directions. The snowmobile has a speed of 13 km/h, while the skier has a speed of 6 km/h. We need to find the distance between the snowmobile and the skier after 2 hours.

Solution

To find the distance between the snowmobile and the skier after 2 hours, we need to calculate the distance covered by each of them in that time.

The snowmobile travels at a speed of 13 km/h for 2 hours, so the distance covered by the snowmobile is: Distance covered by snowmobile = Speed of snowmobile * Time = 13 km/h * 2 hours = 26 km.

Similarly, the skier travels at a speed of 6 km/h for 2 hours, so the distance covered by the skier is: Distance covered by skier = Speed of skier * Time = 6 km/h * 2 hours = 12 km.

Since the snowmobile and the skier are moving in opposite directions, the distance between them is the sum of the distances covered by each of them: Distance between snowmobile and skier = Distance covered by snowmobile + Distance covered by skier = 26 km + 12 km = 38 km.

Therefore, the distance between the snowmobile and the skier after 2 hours is 38 km.
