Answer 2

Problem Analysis

We are given that two pedestrians start walking towards each other simultaneously. The first pedestrian starts from point A and the second pedestrian starts from point B. The first pedestrian walks 1 kilometer more than the second pedestrian and reaches point B after 45 minutes. The second pedestrian arrives at point A 1 hour and 20 minutes after their meeting. We need to find the distance between points A and B.

Solution

Let's assume the distance between points A and B is x kilometers.

We can set up the following equations based on the given information:

Equation 1: The first pedestrian walks 1 kilometer more than the second pedestrian. Equation 2: The first pedestrian reaches point B after 45 minutes. Equation 3: The second pedestrian arrives at point A 1 hour and 20 minutes after their meeting.

Let's solve these equations
