A policeman sees a chain snatcher at a distance of 500 m. He starts chasing the chain snatcher who is running at a speed of 5 m/s, while the policeman is chasing him at a speed of 15 m/s. Find the distance covered by the chain snatcher, when he is caught by the policeman.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 250 m.
Concept used:
Relative speed = x - y, when two objects are moving in the same direction
Calculations:
Distance = 500 m
Relative speed = 15 - 5 = 10 m/s
Time = 500/10 = 50 sec
Distance travelled by the theif in 50 sec = 5 × 50 = 250 m
