Problems on Trains - Quantitative Aptitude (MCQ) questions for Q. 35
Q. A man walks with 3kmph speed in the direction of a train. How much time will a 500m long train take to overtake him at a speed of 63kmph? - Published on 19 Oct 15a. 42 seconds
b. 30 seconds
c. 50 seconds
d. 36 seconds
ANSWER: 30 seconds
Distance to be covered = 500 metres
Effective speed will be equal to difference in the speed of ma and train as they move in opposite directions.
Thus, effective speed = 63kmph-3kmph= 60kmph.
60kmph is equal to 50/3 m/s.
Time = Distance/ Speed
Thus, time taken will be equal to 500/(50/3).
On solving, time = 30 seconds.
Therefore, the train will take 30 seconds to overtake the man.
