  1. Two trains starts simultaneously from the stations A and B towards each other at the rates of u and v
    km/h respectively. When they meet it is found that the second train had traveled x km more than the
    first. Then the distance between the two stations
    (i.e., between A and B) is x(u+v)/ (v-u) km
