Some question: How many seconds will a train 110 meters long take to cross a bridge 150 meters long if the speed of the train is 36 kmph?
Options:
(A) 28 sec
(B) 23 sec
(C) 24 sec
(D) 25 sec
(E) 26 sec
Some stream of consciousness:
D = 110 + 150 = 260
S = 36 * 5/18 = 10 mps
T = 260/10 = 26 sec The answer: (E).
