Question

Пешеход проходит 4 километра . Лыжник на прохождения е километра тратит на 9 минут меньше чем пешеход . Во сколько раз скорость лыжника больше скорости пешехода.

Answer 1

Пешеход проходит 4 км за час (60 минут), значит, 1 км он проходит за 60:4 = 15 минут. Лыжник проходит 1 км за 15-9 = 6 минут. Значит, за час он проходит 60:6 = 10 км.
Скорость лыжника больше скорости пешехода в 10:4 = 2,5 раза.

Answer 2

Calculation of Speed

To determine the ratio of the skier's speed to the pedestrian's speed, we need to compare the distances they cover and the time it takes for each of them to cover their respective distances.

Let's assume that the pedestrian covers a distance of 4 kilometers, and the skier covers a distance of e kilometers. We also know that the skier takes 9 minutes less than the pedestrian to cover their respective distances.

Let's calculate the speed of the pedestrian and the skier:

- Speed of the pedestrian: The pedestrian covers a distance of 4 kilometers. We don't have information about the time it takes for the pedestrian to cover this distance, so we cannot calculate the exact speed of the pedestrian.

- Speed of the skier: The skier covers a distance of e kilometers. We know that the skier takes 9 minutes less than the pedestrian to cover their respective distances. However, we don't have the exact values for e or the time taken by the skier.

Without the exact values for the distances and times, we cannot calculate the exact ratio of the skier's speed to the pedestrian's speed.
