The term (5280 ft/1 mi)  is incorrect
"Feet" needs to be on the bottom to cancel with the previous term. 
"Mile" needs to be on top in the numerator so that the answer can be expressed in "miles per hour"

the correct term is (1 mi/5280 ft)

What is speed?

Speed is distance / time

Here given that Peyton is a sprinter who can run the 40-yard dash in 4.5 seconds

Now speed of peyton can be calculated as = 40/4.5= 400/45= 80/9 yard dash per second

We know that 1 mile =1760 yard dash

and 1 hour = 3600 second

Now speed in into miles per hour can be calculated as :

[tex]\frac{80}{9} \times \frac{3600}{1760} \\\\=18.18\\[/tex]

Hence if Peyton can run the 40-yard dash in 4.5 seconds then his speed  into miles per hour is 18.18
