A train 120 m long passes a man standing on a platform
in 8 seconds. What time (in seconds) will it take to pass completely over a platform 180 m long at the same speed?Solution
ATQ, Speed of train = Distance / Time = 120 / 8 = 15 m/s. To cross a platform, total distance = length of train + length of platform = 120 + 180 = 300 m. Time = 300 / 15 = 20 seconds.
