A policeman follows a thief, who is 150 metres ahead of him, and they run at the speeds of 6 km/h and 5 km/h, respectively. What distance does the policeman cover to catch up with the thief?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 900 metres.
Distance between them = 150 m
Relative speed = 6 − 5 = 1 km/h
1 km/hr = 1 × = m/sec
Time to catch = = 540 seconds
Distance covered by the policeman = 6 × × 540 = 900 meters
