Give a quick stream of consciousness before answering the following question. How long does a train 100 m long traveling at 54 kmph takes to cross a station of 250 m in length?
Options:
(A) 22 sec
(B) 20 sec
(C) 15 sec
(D) 23 sec
(E) 16 sec
D = 100 + 245 = 345 m
S = 54* 5/18 = 15
T = 345 * 1/15 = 23 sec
The answer: (D).
