Question
A train crosses a pole and a platform of length 672
metres in 14 seconds and 30 seconds, respectively. Find the length of train.Solution
Let the speed of train be 'v' m/s.
Length of train = '14v' metres
So, (14v + 672) ÷ 30 = 'v'
Or, 14v + 672 = 30v
Or, 16v = 672
So, 'v' = 42
Therefore, length of the train = 14 × 42 = 588 metres
