Calculating the Time for the Dog to Catch the Cat

To calculate the time it takes for the dog to catch the cat, we can use the formula: time = distance / speed. Given that the distance between the dog and the cat is 30 meters, the dog's speed is 10 meters per second, and the cat's speed is 7 meters per second, we can calculate the time it takes for the dog to catch the cat.

Using the formula: Time = Distance / Speed

We can calculate the time it takes for the dog to catch the cat.

Calculation

Time taken for the dog to catch the cat: 30 meters / (10 meters/second - 7 meters/second) = 30 meters / 3 meters/second = 10 seconds

So, the dog will catch the cat in 10 seconds.

This calculation is based on the given speeds and distances, and it assumes constant speeds for both the dog and the cat.
