A train running at the speed of 60 km/hr crosses a pole in 21 sec. What is the length of the train?
Options:
(A) 350 m
(B) 490 m
(C) 115 m
(D) 210 m
(E) 150 m Now, let's think a bit. Some random thoughts:
Speed = 60 * 5/18 = 50/3 m/sec
Length of the train = speed * time = 50/3 * 21 = 350 m
The final answer: (A).
