Problem Analysis

We are given that a group of boys traveled to a village, covering a distance of 20 km. They traveled at a speed of 5 km/h and returned at a speed twice as fast. We need to determine the total time it took for them to cover this distance.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it took for the boys to travel to the village and back.

1. Time taken to travel to the village: - Distance: 20 km - Speed: 5 km/h - Time = 20 km / 5 km/h = 4 hours

2. Time taken to travel back from the village: - Distance: 20 km - Speed: 2 * 5 km/h = 10 km/h - Time = 20 km / 10 km/h = 2 hours

To find the total time, we add the time taken to travel to the village and the time taken to travel back from the village:

Total time = 4 hours + 2 hours = 6 hours

Therefore, it took the boys 6 hours to cover the distance of 20 km.

Answer

The boys will cover the distance of 20 km in 6 hours.

Verification

Let's verify the solution using the given information.

- The boys traveled to the village at a speed of 5 km/h. The distance is 20 km, so the time taken is 20 km / 5 km/h = 4 hours.- The boys traveled
