Question

Два лыжника вышли одновременно из одного пункта в противоположных направлениях.Скорость одного лыжника 15-км/ч,а другого 10-км/ч.На сколько километров они удалятся друг от друга за 1-ч? за 2-ч? за 3-ч? (Условие)-Краткая запись

Answer 1

За 1 час 15+10=25
удалятся на 25 км
за 2 часа 10*2=20 15*2=30 20+30=50
удалятся на 50 км
за 3 часа 10*3=30 15*3=45 30+45=75
удалятся на 75 км

Answer 2

Calculation of Distance between Two Skiers

To calculate the distance between two skiers who start simultaneously from the same point in opposite directions, we need to consider their speeds and the time elapsed.

Let's assume that one skier has a speed of 15 km/h and the other skier has a speed of 10 km/h.

For 1 hour: - The first skier will cover a distance of 15 km in 1 hour. - The second skier will cover a distance of 10 km in 1 hour. - Therefore, the total distance between them after 1 hour will be 25 km. For 2 hours: - The first skier will cover a distance of 15 km in 2 hours. - The second skier will cover a distance of 10 km in 2 hours. - Therefore, the total distance between them after 2 hours will be 40 km. For 3 hours: - The first skier will cover a distance of 15 km in 3 hours. - The second skier will cover a distance of 10 km in 3 hours. - Therefore, the total distance between them after 3 hours will be 55 km. Please note that these calculations assume that the skiers maintain a constant speed throughout the given time period.
