Problem Analysis

We are given that a pedestrian and a cyclist start from point A and travel to point B, which are 5 km apart. The cyclist starts 30 minutes after the pedestrian and arrives at point B 10 minutes before the pedestrian. We need to find the speeds of the cyclist and the pedestrian.

Solution

Let's assume the speed of the pedestrian is x km/h. Since the cyclist's speed is 10 km/h faster than the pedestrian, the speed of the cyclist is x + 10 km/h.

We can use the formula speed = distance / time to find the time taken by each person to travel from point A to point B.

The time taken by the pedestrian is given by: **time taken by
