Answer 2

Problem Analysis

We are given the following information: - A pedestrian left point A at 9:00. - An hour later, a cyclist left the same point and caught up with the pedestrian at 10:30. - The cyclist then stopped for repairs. - After the repairs, the cyclist continued and caught up with the pedestrian again at 13:00.

We need to determine how much time the repairs took.

Solution

Let's break down the problem step by step:

1. The cyclist caught up with the pedestrian at 10:30, which means they covered the same distance in 1.5 hours. 2. After the repairs, the cyclist caught up with the pedestrian again at 13:00, which means they covered the same distance in 3.5 hours. 3. The time it took for the repairs can be calculated by subtracting the time it took for the second catch-up from the time it took for the first catch-up.

Calculation

To calculate the time it took for the repairs, we subtract the time it took for the second catch-up (3.5 hours) from the time it took for the first catch-up (1.5 hours):

3.5 hours - 1.5 hours = 2 hours

Therefore, the repairs took 2 hours.
