A jogger running at 9 kmph along side a railway track is 240 metres ahead of the engine of a 120 metre long train running at 45 kmph in the same direction. In how much time will the train pass the jogger?
Pick: A) 3.6 sec B) 18 sec C) 36 sec D) 72 sec E) None
CATEGORY   Formulae   Examples   DIRECTIONS : Problems based on Trains.   11.	A train 280 m long, running with a speed of 63 km/hr will pass a tree in   A. 15 sec.   B. 16 sec.   C. 18 sec.   D. 20 sec.   Solution   Speed	= (63 x 5/18) m/sec   = 35/2 msec   Time taken	= (280 x 2 /35)m/sec   = 16 sec.   12.	A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is ihe length of the train?   A. 120 metres   B. 180 metres   C. 324 metres   D. None of these   Solution   13.	A jogger running at 9 kmph alongside a railway track is 240 metres ahead of the engine of a 120 metre long train running at 45 kmph in the same direction. In how much time will the train pass the jogger?   A. 3.6 sec   B. 18 sec   C. 36 sec   D. 72 sec   Solution   Speed of train relative to jogger	= (45 - 9) km/hr   = 36 km/hr   = (36 x 5/18) m/sec   = 10 m/sec   Distance covered	= (240+120)=
