velocity of the train = 15 km/h = 15 × 5/18 = 25/6m/s
Length of the train = 20m
Time taken by the train to cross = 12sec
Total length = length of train + length of station
= 12 × 25/6 = 50m
Length of station = 50m - 20m = 30m
Length of the train = 20m
Time taken by the train to cross = 12sec
Total length = length of train + length of station
= 12 × 25/6 = 50m
Length of station = 50m - 20m = 30m
