A thief is noticed by a policeman from a distance of 150 m. The thief starts running, and the policeman chases him. The thief and the policeman run at the rate of 8 m/s and 10 m/s, respectively. Find the distance travelled by the thief before being caught.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 600 m .
Relative speed = 10 m/s – 8 m/s = 2 m/s
Initial gap = 150 m
Time to catch = 150 / 2 = 75 seconds
Distance travelled by thief = 8 × 75 = 600 meters
