What’s the unit rate for 9miles and 3/4 hr

12 miles per hour.

Step-by-step explanation:

Divide 9 by three (making it the rate for 1/4 hour) then multiply by four. (making it one whole hour.)

9/3 = 3, 3x4 = 12.

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
