Question

велосепедист двигаясь равномерно проезжает за 4 секунды 40м.Какой путь он проедет при движении в той же скоростью за 15 секунд?

Answer 1

Problem Analysis

We are given that a cyclist travels a distance of 40 meters in 4 seconds while moving at a constant speed. We need to determine the distance the cyclist will travel in 15 seconds at the same speed.

Solution

To solve this problem, we can use the formula for calculating distance:

Distance = Speed × Time

Given that the cyclist is moving at a constant speed, we can assume that the speed remains the same. Therefore, we can use the ratio of the times to find the ratio of the distances.

Let's calculate the distance the cyclist will travel in 15 seconds.

Calculation

The ratio of the times is:

4 seconds : 15 seconds

To find the ratio of the distances, we divide the time ratio by the same value:

40 meters : ?

Using the ratio of the times, we can set up a proportion:

4 seconds / 15 seconds = 40 meters / x

To solve for x, we can cross-multiply and then divide:

4 seconds × x = 15 seconds × 40 meters

x = (15 seconds × 40 meters) / 4 seconds

Simplifying the expression:

x = 150 meters

Answer

Therefore, the cyclist will travel a distance of 150 meters in 15 seconds at the same speed.
