    Answer: the joggers average speed is 9 miles per hour.

    Step-by-step explanation:

    A jogger runs for half an hour and a distance of 4 miles.

    Speed = distance/time

    Therefore, the speed of the jogger for the first half hour is

    4/0.5 = 8 miles per hour

    The jogger rest for one hour. Then the jogger runs for half an hour and the distance of 5 miles.

    Therefore, the speed of the jogger for the second half hour is

    5/0.5 = 10 miles per hour

    The average speed of the jogger would be

    (8 + 10) / 2 = 18/2 = 9 miles per hour.
