A robber steals a bag from a man at 5 p.m. and starts running at 10 km/h. A policeman is informed about the robber at 5 : 12 p.m. and he chases him on a cycle at 15 km/h. At what time is the robber caught by the policeman?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 5:36 p.m.
Given that
Speed of the robber = 10 km/h
⇒ Distance covered by the robber in 12 minutes = × 10 = 2 km
The relative speed of the robber and the policeman = 15 - 10 = 5 km/h
Formula used
⇒ Speed =
Hence the time taken to cover the distance of 2 km = hrs = 24 minutes
Hence, the robber is caught 24 minutes 5 : 12 i.e. 5 : 36 pm.
