Answer:

Smallest: 15,840 ft

Largest: 16,896 ft

Step-by-step explanation:

1 mi = 5,280 ft

Setup proportion to solve for the smallest:

[tex]\frac{1mi}{5,280ft} =\frac{3mi}{xft}[/tex]

Do butterfly method and you should get this:

[tex]xft=3(5280)\\x=15,840ft[/tex]

Setup proportion to solve for the largest:

[tex]\frac{1mi}{5,280ft} =\frac{3.2mi}{xft}[/tex]

Butterfly method:

[tex]xft=3.2(5280)\\x=16,896ft[/tex]
