    The east bound train travels at a speed of 95 mile per hour and the west bound train at 75 miles per hour.

    Assuming eastbound train will cover distance x then the west bound train will cover distance 272-x.

    Therefore, since time taken will be the same then; x/95 = (272-x) / 75

    = 75x = 95 (272-x)

    = 75x = 25840 - 95x

    = 170 x = 25840

    x = 152 miles

    Thus time taken will either be x/95 or (272-x) / 75

    = 152/95

    = 1.6 hours or 1 hour 36 minutes
