How many seconds will a train 100 meters long take to cross a bridge 120 meters long if the speed of the train is 36 kmph?\nOptions:\n(A) 54 sec\n(B) 65 sec\n(C) 25 sec\n(D) 22 sec\n(E) 24 sec
Let's be accurate as possible. Think before you answer.
(D)
D = 100 + 120 = 220\nS = 36 * 5/18 = 10 mps\nT = 220/10 = 22 sec.

So, the answer is (D)
