1. convert: 3 ½ mi = ft. 18,480 1508 ½ 213 10 ½

Convert: 3 ½ mi = ft.
                                                                     5280 ft
I'd prefer to use a conversion factor:   1 =
                                                                      1 mile

Thus,

3 1/2 miles      5280 ft
* = 18480 ft (answer) 
           1            1 mile

A= the square root of 3“if letters are anything like people, they’re all equal and deserve to be treated equally.”
