Problem Analysis

To solve this problem, we need to determine the time it takes for the dog to catch up with the fox. We are given the speeds of the dog and the fox, as well as the initial distance between them. We can use this information to calculate the time it takes for the dog to catch up with the fox.

Solution

Let's break down the problem step by step:

1. Calculate the relative speed between the dog and the fox: - The dog's speed is 400 meters per minute. - The fox's speed is 320 meters per minute. - The relative speed between the dog and the fox is the difference between their speeds: 400 - 320 = 80 meters per minute.

2. Calculate the time it takes for the dog to catch up with the fox: - The initial distance between the dog and the fox is 720 meters. - To catch up with the fox, the dog needs to cover this distance. - We can calculate the time it takes for the dog to catch up with the fox by dividing the initial distance by the relative speed: 720 / 80 = 9 minutes.

Answer

The dog will catch up with the fox in 9 minutes.
