Question

A .Dog and a cat are 200 meters apart when they see each other. The dog can run at a speed of 30 m/sec, while the cat can run at a speed of 24 m/sec. How soon will the dog catch the cat if the dog starts running after the cat?

Answer 1

33 ¹/₃ seconds

Explanation:

Since the dog is 30 - 24 = 6 m/s faster than the cat, that means that the dog is 6 meters closer to the cat each second.

So, that gap will close in 200/6 = 33 ¹/₃ seconds.
