A jogger running at 9 kmph alongside a railway track in 240 metres ahead of the engine of a 120 metres long train running at 45 kmph in the same direction. In how much time will the train pass the jogger?

Answer: 36 Sec
Explanation

Speed of train relative to jogger = (45−9) km/hr = 36 km/hr

=(36×185​)m/sec

10 m/sec.

Distance to be covered = (240+120)m=360m.

 Time taken =(10360​)sec

=36sec.
