Verified Answer
If a 150 m long train crosses a platform, which is 20% longer than the...
Length of platform = (100 + 20)% of (length of train) = 1.2 × 150 = 180 m
As we know, Time taken to cross the platform = (sum of lengths of train and platform)/speed of train
⇒ 30 = (150 + 180)/(Speed of train)
∴ Speed of train = 330/30 = 11 m/sec = 11 × (18/5) = 39.6 km/hr
