Question

How can I do this I'm so stuck on this plz help

Answer 1

You're just changing the given rate into a unit rate: follow along and do the division shown and fill in the blanks. 320 ÷16 = 20

So the unit rate is $\frac{20mi}{1gal}$

Answer 2

Do 320/16 and that will equal 20 and don’t pay attention to the denominators because they already put a 1 for you.
