Calculation of the Time it Takes for the Dog to Catch up to the Cat

To calculate the time it takes for the dog to catch up to the cat, we can use the formula:

Time = Distance / Speed

Given that the distance between the dog and the cat is 30 meters, the speed of the dog is 10 m/s, and the speed of the cat is 7 m/s, we can substitute these values into the formula to find the time it takes for the dog to catch up to the cat.

Time = 30 meters / (10 m/s - 7 m/s)

Simplifying the equation:

Time = 30 meters / 3 m/s

Therefore, the time it takes for the dog to catch up to the cat is 10 seconds.
