Question
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: Option C
- Speed of train relative to jogger = (45 - 9) km/hr = 36 km/hr
= 36 x 5 m/sec 18
= 10 m/sec.
Distance to be covered = (240 + 120) m = 360 m
Time taken = 360 sec = 36 sec. 10
