Problem Analysis

We are given that a dog is chasing a fox, with the fox initially 480 meters ahead of the dog. The fox runs at a speed of 320 meters per minute, while the dog runs at a speed of 350 meters per minute. We need to determine how many minutes it will take for the dog to catch up to the fox.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's calculate the time it will take for the dog to catch up to the fox.

Calculation

The distance between the dog and the fox is initially 480 meters. The fox runs at a speed of 320 meters per minute, while the dog runs at a speed of 350 meters per minute.

Using the formula Time = Distance / Speed, we can calculate the time it will take for the dog to catch up to the fox:

Time = 480 meters / (350 meters/minute - 320 meters/minute)

Simplifying the expression inside the parentheses:

Time = 480 meters / 30 meters/minute

Calculating the division:

Time = 16 minutes

Therefore, it will take the dog approximately 16 minutes to catch up to the fox.

Answer

The dog will catch up to the fox in approximately 16 minutes.
