A man started running at a distance of 225 metre from the train. If the speed of the man is 6 km/h, then how much time should the train wait so that the man will be just able to catch it ?
Options:
(A) 2 14 min
(B) 3 min
(C) 4 14 min
(D) 4 12 min
(E) None of these Hmmm, my stream of consciousness:
Time = 225/6518 = 135 sec = 214 min. So, the answer is (A).
