- Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr.
Question 1:
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. The length of each train is: A. 50 m
Feedback Let the length of each train be x metres
Then, distance covered = 2x metres.
Relative speed = (46 - 36) km/hr
(10 x 5/18)m/sec
25/9 m/sec
2x /36 = 25/9
x = 50.
Then, distance covered = 2x metres.
Relative speed = (46 - 36) km/hr
(10 x 5/18)m/sec
25/9 m/sec
2x /36 = 25/9
x = 50.
B. 72 m
C. 80 m
D. 82 m
