Question
A train crosses a pole and a platform of length 360 metres
in 6 seconds and 18 seconds, respectively. Find the length of train.Solution
Let the speed of train be 'v' m/s.
Length of train = '6v' metres
So, (6v + 360) ÷ 18 = 'v'
Or, 6v + 360 = 18v
Or, 12v = 360
So, 'v' = 30
Therefore, length of the train = 6 × 30 = 180 metres
