3 miles per hour. Theres 4 hours between 9 am and 12 and another 6 from 1to 6.so ten hours. then 12.8 plus 17.8 thats 30 then 30 divided by ten is 3 miles per hour. Your welcome :)

(12.8+17.2)/((12-9)+(6-1))
30/(3+5)
30/8
15/4
3.75mph
It's been awhile since I've done this type of math but I hope I got it right.
