The pedestrian moved at a speed of 4 km / h and arrived at the destination in 3 hours. At what speed should he go back to overcome it in 2 hours?
To solve the problem, you first need to determine how far the pedestrian traveled to the destination.
To do this, we multiply the speed of its movement by the travel time.
We get:
4 * 3 = 12 km.
In order to determine the speed with which a pedestrian must move in order to cover this distance in 2 hours, we divide the distance by the travel time.
We get:
12/2 = 6 km / h.
Answer: A pedestrian must walk at a speed of 6 km / h.
