A jogger running at 9 km/hr alongside a railway track is 240 metres ahead of the engine of a 120 metres long train running at 45 km/hr in the same direction. In how much time will the train pass the jogger?
সমাধান
সঠিক উত্তর: Option C
Speed of train relative to jogger = (45 - 9) km/hr = 36 km/hr.
=36/18 x 5m/sec = 10 m/sec.
Distance to be covered = (240 + 120) m = 360 m.
Time taken = 360 sec = 36 sec.
