A train running at the speed of 60 km/hr crosses a pole in 15 sec. What is the length of the train?
Options:
(A) 356
(B) 250
(C) 127
(D) 279
(E) 150 Let's think first. Stream of consciousness:
Speed = 60 * 5/18 = 50/3 m/sec
Length of the train = speed * time = 50/3 * 15 = 250 m
So, the answer is (B).
