Give a quick stream of consciousness before answering the following question. A train running at the speed of 60 km/hr crosses a pole in 9 sec. What is the length of the train?
Options:
(A) 356
(B) 278
(C) 127
(D) 279
(E) 150
Speed = 60 * 5/18 = 50/3 m/sec
Length of the train = speed * time = 50/3 * 9 = 150 m
The answer: (E).
