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 18 seconds. The length of each train is:  Pick
A) 25m B) 50m C) 72m D) 80m 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 18 secs the total distance traveled is 18x25/9 = 50 m.   Therefore the length of each train is = 50/2=
