Question:
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
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.
