    Two trains of equal length are running on parallel lines in the same direction at the rate of 46 km/h and 36 km/h. The faster train passes the slower train in 36 s. The length of each train is

    A)  50 m            

    B)  80 m

    C)  72 m            

    D)  None of these

    Correct Answer: A

    Solution :

    Speed of faster train relative to slower one \[=(46-36)\,km/h=\left( 10\times \frac{5}{18} \right)m/s\] \[=\frac{25}{9}m/s\] Distance covered in \[36s=\left( \frac{25}{9}\times 36 \right)=100\,m\] \[\therefore \] 2 (length of each train) = 100 m \[\therefore \] length of each train = 50 m
