A yard is equal to 3 feet. So knowing this we multiply 5280 which is how many feet are in a mile by 2.5 that is the miles we will take into consideration.
5280 x 2.5= 13,200
Now this value we divide it by 3 which is how long a yard is in terms of ft measurement.
[tex] \frac{13200}{3} = 4400 \: yards[/tex]
