Two trains of equal length are running on parallel lines in the same direction at 46 km/hr. and 36 km/hr. The faster train passes the slower train in 36 seconds. Find the length of each train.

A40 m

B50 m

C100 m

D95 m

Answer:

B. 50 m

Read Explanation:

Let the length of each train be x metres. Then, distance covered = 2x metres. Relative speed = (46 - 36) km/hr=10 x5/18m/sec=25/9 m/sec 2x/36=25/9 2x = 100 x = 50.
