Hi

Let t represent the time it takes for trains to be 378mi apart

Question states*** Trains traveling in opposite directions.  D = r*t

  95t + 115t = 378

      210t = 378mi

        t = 378/210 = 1.8hr,time it takes for trains to be 378mi apart

 

 CHECKING our Answer***

 95mp*1.8hr + 115mph*1.8hr  = 378mi
