Question

Пешком от дома до школы Никита добирается за 16 минут, а его друг Саша добегает до школы и обратно за 8 минут, не останавливаясь. Во сколько раз скорость Саши превышает скорость Никиты?

Answer 1

1) 16:2=8(раз)
ответ: скорость Саши превышает скорость Никиты в 8раз

Answer 2

Calculation of Speed

To determine the ratio of Sasha's speed to Nikita's speed, we need to calculate their respective speeds first.

Nikita takes 16 minutes to walk from home to school, which we'll consider as the distance between the two points. Sasha, on the other hand, runs from home to school and back in a total of 8 minutes, without stopping.

Let's calculate their speeds:

- Nikita's speed: Distance / Time = 1 / 16 = 0.0625 units per minute. - Sasha's speed: Distance / Time = 2 / 8 = 0.25 units per minute.

Ratio of Sasha's Speed to Nikita's Speed

To find the ratio of Sasha's speed to Nikita's speed, we divide Sasha's speed by Nikita's speed:

Sasha's speed / Nikita's speed = 0.25 / 0.0625 = 4.

Therefore, Sasha's speed is 4 times faster than Nikita's speed.
