A 150 m long train is running with a speed with a speed of 68 kmph. In what time will it pass a man who is running at 8 kmph in the same direction as that of the train ?
Answer & explanation
Correct answer: option 3
Relative speed ( Move in same direction ) = 68 - 8= 60 kmph
= 60 × \(\frac{5}{18}\) m/sec
= \(\frac{50}{3}\) m/sec
Time taken by train to cover 150 m
= \(\frac{Distance }{Speed}\)
= \(\frac{150 ×3}{50}\)
= 9 sec
The correct answer is option (3) : 9 sec
