A dog starts chasing a rabbit that is 200 meters away. The dog runs at 25 m/s, and the rabbit runs at 20 m/s. How far will the rabbit have run before the dog catches it?
Show answer & explanation
Correct answer: A
Explanation
Given:
Speed of the dog = 25 m/s
Speed of the rabbit = 20 m/s
Initial distance = 200 m
Formula:
Time = Distance / Relative speed
Relative speed = 25 − 20 = 5 m/s
Time = 200 / 5 = 40 seconds
Distance covered by the rabbit = 20 × 40 = 800 m
