After seeing a policeman from a distance of 500 m, a thief starts running at a speed of 10 km/h. After noticing, the policeman chases immediately with a speed of 12 km h, and the thief is caught. The distance run by the policeman is:
Explanation:
Initially the distance between policeman and thief = 500m = 0.5 km
Relative speed of policeman with respect to thief = 12 - 10 = 2 kmph
Time taken by the policeman to catch the thief = 0.5/2 = 0.25 hours.
∴ The distance covered by the policeman = 0.25 × 12 = 3 kms
Hence, option (c).
