A jogger is running at 9 kmph alongside a railway track in 240 metres ahead of the engine of a 120 metres long train. The train is running at 45 kmph in the same direction. How much time does it take for the train to pass the jogger?

Distance to be covered =(240+120) =360 m
Relative speed =(45−9)=36 km/hr
=36 × 5/18 =10 m/s
Required time = 360/10 = 36 seconds
