    Average speed = total distances / total time

    3115.8 / 7.2 = 432.75 mi/h

    Formula for speed = Distance/Time

    Now that we know that, the distance the plane flew is 3115.8 miles and the time was 7.2 hours

    So we arrange it like this:

    3115.8 / 7.2

    Now if we use a calculator, your answer should be ...

    432.75 mph
