Question

What conversion factor is needed to complete the work shown below to convert 253440 inches to miles​

Answer 1

1 mile over 5,280 feet

Explanation:

Answer 2

1 mile = 63,360in

or

`(1mile)/(63,360in)`

Explanation:

There are 5,280 feet in 1 mile

There are 12 inches in 1 foot

You can do this by converting twice:

`253,440in* (1ft)/(12in)* (1mi)/(5,280ft)= 4miles`

If you want a straight conversion factor then, you can take it from the above equation:

`253,440in* (1ft)/(12in)* (1mi)/(5,280ft)\\\\253,440in* (1mi)/(63,360in)=4miles`
