Two trains are traveling in opposite directions at 90 kmph and 18 kmph. If the length of the faster train is 600 m, find the time taken by the faster train to cross a man standing in the slower train.

As the faster train crosses the man in the slower train,

time taken in this case = length of the faster train / Relative speed.
Thus time = 600 / 30 = 20 seconds.

Hence, option 1 is the correct answer.
