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 54 seconds. The length of each train is:
Choose the correct answer
A) 82m  B) 50m  C) 75m  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 54 secs the total distance traveled is 54x25/9 = 150 m.   Therefore the length of each train is = 150/2=

<output>75</output>
75 m.   Answer 75m
