A policeman started following a thief who was 1,200 metres ahead of him. The thief is running at 2.5 km/h, while the speed of the policeman is 3.75 km/h. Find the distance covered by the thief (in metres) just when he was caught.
Show answer & explanation
Correct answer: B
Explanation
Given:
Initial distance = 1200 m
Speed of the thief = 2.5 km/h
Speed of the policeman = 3.75 km/h
By the formula:
Time = Distance ÷ Relative speed
Relative speed = 3.75 − 2.5 = 1.25 km/h
Time = 1.2 ÷ 1.25 = 0.96 hours
Now the distance covered by the thief = 2.5 × 0.96 = 2.4 km
In meters = 2400 m
