Question

Поезд, идущий со скоростью 68 км/ч, проходит расстояние между городами за 6 часов. Какое время потребуется велосипедисту, чтобы проехать 1/8 этого расстояния со скоростью 17 км/ч

Answer 1

Расстояние между городами 68*6=408км 1/8 от этого расстояния =408/8=51км 51/17=3 часа

Answer 2

Calculating Time Required for a Cyclist to Cover a Fraction of the Distance

To calculate the time required for a cyclist to cover 1/8 of the distance between the cities at a speed of 17 km/h, we can use the formula:

Time = Distance / Speed

Given: - Speed of the train = 68 km/h - Time taken by the train to cover the distance = 6 hours

First, let's calculate the distance between the cities using the speed and time taken by the train.

Calculating the Distance Between the Cities

The distance covered by the train can be calculated using the formula:

Distance = Speed × Time

Using the given speed and time taken by the train, we can calculate the distance covered by the train.

Distance = 68 km/h × 6 h

Distance = 408 km

Now that we have the distance between the cities, we can calculate the time required for the cyclist to cover 1/8 of this distance at a speed of 17 km/h.

Calculating the Time Required for the Cyclist

Using the formula Time = Distance / Speed, we can calculate the time required for the cyclist to cover 1/8 of the distance.

Time = (1/8) × 408 km / 17 km/h

Time = 51 km / 17 km/h

Time = 3 hours

Therefore, the cyclist would require 3 hours to cover 1/8 of the distance between the cities at a speed of 17 km/h.
