Problem Analysis

We are given that a cyclist travels at a speed of 7 km/h and covers a distance of 21 km. Another cyclist starts from the opposite direction with a speed of 10 km/h. We need to find the time it takes for each cyclist to be 6 km apart.

Solution

Let's calculate the time it takes for each cyclist to be 6 km apart.

The first cyclist travels at a speed of 7 km/h, so the time it takes for the first cyclist to cover a distance of 21 km is:

Time taken by the first cyclist = Distance / Speed = 21 km / 7 km/h = 3 hours.

The second cyclist travels at a speed of 10 km/h. We need to find the time it takes for the second cyclist to cover a distance of 6 km.

Time taken by the second cyclist = Distance / Speed = 6 km / 10 km/h = 0.6 hours = 36 minutes.

Therefore, the first cyclist takes 3 hours and the second cyclist takes 36 minutes to be 6 km apart.

Answer

The first cyclist takes 3 hours and the second cyclist takes 36 minutes to be 6 km apart.
