Two trains of equal length are running on parallel lines in the same directions at 46km/hr. and 36km/hr. The faster trains pass the slower train in 108 seconds. The length of each train is:	Choose the correct choice from the following answers:
A) 82m
B) 50m
C) 72m
D) 150m
E) None of these
Explanation:   The relative speed of train is 46-36=

10 Km/hr= (10 X 5) / 18 = 25/9 m/s10×518=259m/s   In 108 secs the total distance traveled is 108x25/9 = 300 m.   Therefore the length of each train is = 300/2=
