# A pedestrian and a cyclist started moving from two points simultaneously in the same direction.

**A pedestrian and a cyclist started moving from two points simultaneously in the same direction. a cyclist moves at a speed of 20 km / h, a pedestrian 5 km / h. the distance between them is 18 km. How many hours after the start of the movement will the cyclist catch up with the pedestrian?**

1. Let us determine how many kilometers per hour the speed of a cyclist is greater than the speed of a pedestrian, if the cyclist moves at a speed of 20 kilometers per hour, and a pedestrian moves at a speed of 5 kilometers per hour:

20 – 5 = 15 (km / h).

2. Find out how long after the start of the movement the cyclist will catch up with the pedestrian, if the distance between the points is 18 kilometers, and the cyclist’s speed is 15 kilometers per hour more than the pedestrian’s speed:

18:15 = 1.2 (h).

Answer: in 1.2 hours.
