    Train 1 have traveled for 14 hours at a rate of 65mph

    => it has traveled 65*14=910miles

    this means that the train have traveled 910miles away from the station.

    Since the 2 rains are 1960miles apart and opposite in direction

    => the second train is 1960-910=1050miles away from the station

    It is traveling at rate75m/hr

    =>time=d/v=1050/75=14 hours

    => they have launched at the same time.

    Yet the second train was traveling at a higher speed thus traveled a bigger distance
