Question

Can any help me with these

Answer 1

I can only clearly see #5.

A mile has 5,280 feet.

Divide 18,472 by 5,280.
18,472 / 5,280 = 3.5

18,472 feet is about 3.5 miles.

Answer 2

4.) 1 mile = 5280 feet

I like to put the equation like this because it's much more easier:

1 mile = 5280 feet / ?? miles = 18,472

Multiply 5,280 by 18,472, and divide by 1 equals, 97,532,160 miles.
