    Answer: 67.5 mph

    Step-by-step explanation:

    The formula for speed is:

    = Distance / Time

    Distance = 658.125 miles

    Time will need to be converted to a decimal. You may convert only the minutes into hours as the hours are already hours.

    = 45/60 minutes

    = 0.75 hrs

    = 9 + 0.75

    = 9.75 hours

    Speed = 658.125 / 9.75

    = 67.5 mph
