Correct answer: B
Answer:
400 meters
Explanation:
We can safely assume that the policeman is running in the same direction as the thief.
Speed of policeman w.r.t thief = (10 – 8) = 2 km/hr.
Time taken by policeman to cover the 100m distance between him and the thief = (100/1000) / 2 = 1/20 hr.
Therefore, the distance covered by thief in 1/20 hrs = 8 × 1/20 = 2/5 km = 400 meters.
