Problems on Two trains are repeatedly asked in competitive exams like SSC-CGL, SSC-CHSL, MBA CAT Exams and GMAT exams. If you are preparing for Quantitative Aptitude, the problems of two train are must to practice.
A train 110 m long is running with a speed of 60 kmph. In what time will it pass a man who is running at 6 kmph in the direction opposite to that in which the train is going?
Given: Length of train = 110m
Speed of train = 60 kmph
Speed of man = 6 kmph
Now, Speed of train relative to man = (60 + 6) kmph (add since both are running opposite to each other)
= 66 kmph
= 66x (1000/3600) = 55/3 m/sec
Therefore, time taken to pass the man = distance/speed = 110/ (55/3) = 6 sec
Train will take 6 sec to pass through the man
