Problem Analysis

We are given that a dog is chasing a cat, and at a certain point, there is a distance of 9 km between them. The cat's speed is 3 m/s, and the dog's speed is 4 m/s. After running 24 m, the cat climbs a tree. We need to determine the distance between the dog and the tree at that moment.

Solution

To find the distance between the dog and the tree, we need to calculate the remaining distance that the dog needs to cover after the cat climbs the tree.

Let's break down the problem step by step:

1. Calculate the time it takes for the cat to reach the tree: - Distance = Speed × Time - Time = Distance / Speed - Time = 24 m / 3 m/s = 8 seconds

2. Calculate the distance the dog covers in 8 seconds: - Distance = Speed × Time - Distance = 4 m/s × 8 s = 32 meters

Therefore, the dog is 32 meters away from the tree when the cat climbs it.

Answer: The dog is 32 meters away from the tree at that moment.
