A train running at 25 km/hr takes 18 seconds to pass a platform. Next, it takes 12 seconds to pass a man walking at 5 km/hr in the same direction. Find the length of the train.
Choose the most appropriate option:	A) 200/3m	B) 100m	C) 50m	D) 100/3	E) none of these
A train running at 25 km/hr takes 18 seconds to pass a platform. Next, it takes 12 seconds to pass a man walking at 5 km/hr in the same direction. Find the length of the train and that of the platform.   Distance = Speed*time   The man is moving forward at a speed of 5km/h while the train is moving forward at a speed of 25km/h. Therefore, the train is moving past the man at a total speed of 20km/h.   distance = speed * time   distance = 20km/h * 12 seconds   distance (length of train) = 66.6 m   200/3mNSWER: 200/3m) 200/3m
