Problem Analysis

Two pedestrians start walking towards each other from points A and B simultaneously. They meet after 40 minutes and the first pedestrian arrives at point B 32 minutes after the meeting. We need to determine how many hours after starting from point A the second pedestrian arrives at point B.

Solution

Let's break down the problem step by step:

1. The two pedestrians meet after 40 minutes. This means that the total time they have been walking is 40 minutes. 2. After the meeting, the first pedestrian arrives at point B 32 minutes later. This means that the first pedestrian has been walking for a total of 40 + 32 = 72 minutes. 3. To find out how many hours the second pedestrian takes to reach point B, we need to subtract the time the first pedestrian took from the total time they have been walking. So, the second pedestrian takes 40 - 32 = 8 minutes to reach point B. 4. To convert minutes to hours, we divide the time in minutes by 60. Therefore, the second pedestrian takes 8 / 60 = 0.1333 hours to reach point B.

Therefore, the second pedestrian arrives at point B approximately 0.1333 hours after starting from point A.

Answer

The second pedestrian arrives at point B approximately 0.1333 hours after starting from point A.
