    Two trains, each 50 m long are travelling in opposite direction with velocity 10 m/s and 15 m/s. The time of crossing is:

    A)  \[\frac{10}{3}s\]                                             

    B)        \[2\,s\]                

    C)         \[2\sqrt{3}\,s\]                               

    D)         \[2\sqrt{3}\,s\]

    Correct Answer: A

    Solution :

    From the formula \[\text{Time}\,\text{=}\frac{\text{total}\,\text{distance}}{\text{relaive}\,\text{velocity}}\] \[=\frac{50+50}{15+15}\,=\frac{100}{30}\,=\frac{50}{3}\,\sec \]
