Answer: 5.33 miles per hour.

Explanation:

You know:
(4)/(5) of a mile in nine minute.

Then:

You need to convert 9 minutes to hours (Remember that there is sixty minutes in one hour). Then:


(9min)((1hour)/(60minutes))=(9)/(60)hours

Now, you need to divide
(4)/(5)miles by
(9)/(60)hours.

Therefore, the unit rate in miles per hour is:


=((4)/(5)miles)/((9)/(60)hours)\\\\=((4*60)/(5*9))\\\\=5.33(miles)/(hour)

(5.33 miles per hour)
