    Driving Word Problem

    John and Mary leave their house at the same time and drive in opposite directions. John drives at 50 mi/h and travels 35 mi farther than Mary, who drives at 40 mi/h. Mary's trip takes 15 min longer than John's. For what length of time does each of them drive? (Round each answer to two decimal places.)

    Mary drives for 15 minutes longer.
    Given that she's driving at 40 miles per hour, this gives her an extra ten miles.

    So, when John stops, he has travelled 45 miles more than Mary.


    You can finish from here?
