Question
A train crosses a pole and a platform of length 624
metres in 13 seconds and 29 seconds, respectively. Find the length of train.Solution
Let the speed of train be 'v' m/s.
Length of train = '13v' metres
So, (13v + 624) ÷ 29 = 'v'
Or, 13v + 624 = 29v
Or, 16v = 624
So, 'v' = 39
Therefore, length of the train = 13 × 39 = 507 metres
