Solution :
Length of the first train = 200 m Length of the second train = 300 m Relative speed of the train \[=\,\,\,(68-50)=18\,km/hr\] \[=\,\,\,\,\,18\times \frac{5}{18}=5m.\,/\sec .\] Time taken by trains to cross each other \[=\frac{200+300}{5}=\underline{\mathbf{100}\,\mathbf{sec}\mathbf{.}}\]You need to login to perform this action.
