Two trains travel in opposite direction at 32 km/h and 40 km/h and a man sitting in slower train passes the faster train in 6 s. The length of the faster train is?
Correct Answer: 120 m
Explanation:
Relative speed = (32 + 40) = 72 km/h = (72 x 5/18) m/s = 20 m/s
∴ Length of train = (20 x 6) = 120 m
