Give stream of consciousness and then the final answer. A train running at the speed of 142 km/hr crosses a pole in 12 seconds. Find the length of the train.
Options:
(A) 540
(B) 288
(C) 200
(D) 340
(E) 712
Speed = 162*(5/18) m/sec = 45m/sec
Length of Train (Distance) = Speed * Time
45 * 12 = 540 meter
The final answer: (A).
