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?
- 3.6 Sec
- 18 Sec
- 36 Sec
- 72 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.
