Question

Два лыжника шли друг за другом на расстоянии 200м со скоростью 100м.мин каждый.Когда лыжники стали подниматься в гору, скорость каждого уменьшилась до 60.мин . Какое расстояние стало между ними???????????

Answer 1

Расстояние осталось прежним(200м), т.к. отношение скоростей до поднятие на гору и после равно 1.

Calculation of the Distance between Skiers

To calculate the distance between the two skiers, we need to consider their initial distance and their speeds before and after they started going uphill.

Given: - Two skiers are walking one after the other at a distance of 200 meters. - The initial speed of each skier is 100 meters per minute. - When they start going uphill, the speed of each skier decreases to 60 meters per minute.

To find the distance between the skiers after they start going uphill, we can use the following steps:

1. Calculate the time it takes for the skiers to reach the uphill section: - The time it takes for the skiers to reach the uphill section is the same for both skiers since they are walking at the same speed. - Using the formula `time = distance / speed`, the time it takes for the skiers to reach the uphill section is `200 meters / 100 meters per minute = 2 minutes`.

2. Calculate the distance covered by each skier during the uphill section: - The distance covered by each skier during the uphill section is the product of their speed and the time it takes to reach the uphill section. - For each skier, the distance covered during the uphill section is `60 meters per minute * 2 minutes = 120 meters`.

3. Calculate the distance between the skiers after they start going uphill: - The distance between the skiers after they start going uphill is the initial distance minus the distance covered by each skier during the uphill section. - The distance between the skiers after they start going uphill is `200 meters - 120 meters = 80 meters`.

Therefore, the distance between the two skiers after they start going uphill is 80 meters.
