Give a quick stream of consciousness before answering the following question. A Train requires 8 seconds to pass a pole while it requires 18 seconds to cross a stationary train which is 400 mtrs long. Find the speed of the train.
Options:
(A) 144 kmph
(B) 124 kmph
(C) 134 kmph
(D) 150 kmph
(E) 160 kmph
In 8s the train crosses the pole and in 18 sec the train crosses one more stationary train
In 10 sec the train travels a distance of 400 mtrs
Speed = 400/10 = 40 m/s = 40 (3600/1000) = 40 * 18/5 = 144 kmph
The answer: (A).
