I need to change Linear units.

What is 3,520 yd = to How many mile?

Divide 3520 yards by 1760 yards/mile.
Looks like you'll get a nice round number.

To convert 3,520 yards to miles, you can divide the number of yards by the number of yards in a mile. The conversion factor is 1 mile = 1760 yards.

So, you need to divide 3,520 yards by 1,760 yards/mile to get the equivalent distance in miles.

3,520 yards / 1,760 yards/mile = 2 miles

Therefore, 3,520 yards is equal to 2 miles.
