    Two trains start running in opposite direction from two places and reach the destination mid-point after \[3\frac{1}{3}\] hours and \[4\frac{4}{5}\] hours. If the speed of the first train is \[80\text{ }km/hr,\]then what is the speed of the 2nd train (in km/hr)?

    A)  641                            

    B)  661

    C)  55 

    D)  75

    Correct Answer: C

    Solution :

     Speed of 2nd train \[=\frac{Distance\text{ }covered\text{ }by\text{ }1st\text{ }train}{Time\text{ }taken\text{ }by\text{ }2nd\text{ }train}\] \[=\frac{\frac{10}{3}\times 80}{\frac{24}{5}}=\frac{800}{3}\times \frac{5}{24}=\]
