Answer:
1 mile = 63,360in
or
[tex]\dfrac{1mile}{63,360in}[/tex]
Step-by-step explanation:
There are 5,280 feet in 1 mile
There are 12 inches in 1 foot
You can do this by converting twice:
[tex]253,440in\times \dfrac{1ft}{12in}\times \dfrac{1mi}{5,280ft}= 4miles[/tex]
If you want a straight conversion factor then, you can take it from the above equation:
[tex]253,440in\times \dfrac{1ft}{12in}\times \dfrac{1mi}{5,280ft}\\\\253,440in\times \dfrac{1mi}{63,360in}=4miles[/tex]
