A policeman sees a thief at a distance of 100 m and starts chasing him at a speed of 6 m/s while the thief runs at a speed of 5 m/s. What is the distance (in m) covered by the thief when he is caught?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 500.
Relative speed = 6 – 5 = 1 m/s
Distance between them = 100 m
Time to catch = 100 ÷ 1 = 100 s
In 100 s, thief runs = 5 × 100 = 500 m
