    Two trains start from stations A and B and travel towards each other at speeds of 50 km/h and 60 km/h respectively. At the time of their meeting, the second train has travelled 120 km more than the first. The distance between A and B is

    A)  990 km            

    B)  1200 km

    C)  1320 km          

    D)  1440 km

    Correct Answer: C

    Solution :

    Let train A start from station A and B from station B. Let the trains A and B meet after t h. \[\therefore \] Distance covered by train A in \[t\,\,h=50\,t\] Distance covered by train B in \[t\text{ }h=60\,t\,\,km\] According to the question, \[60\,t-50\,t=120\] \[\Rightarrow \]   \[t=\frac{120}{10}=12\,\,h\] \[\therefore \] Distance\[AB=50\times 12+60\times 12\]             \[=600+720\] \[\Rightarrow \]   \[=1320\text{ }km\]
