    A train of 130 m length is running at a speed of 45 km/h and crosses a bridge in 30 s. What is the length of the bridge?

    A)  200 m 

    B)  225 m

    C)  245 m 

    D)  250 m

    Correct Answer: C

    Solution :

    Length of bridge = x metre, then \[\frac{(x+130)60\times 60}{45\times 1000}=30\] \[\Rightarrow \]   \[x+130=375\] \[\therefore \]      \[x=245\,\,m\]
