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
=> they have launched at the same time.
Yet the second train was traveling at a higher speed thus traveled a bigger distance
