E Question Help You are running a fuel economy study. One of the cars you find is blue. It can travel 40, miles on 1 2 1 1 4 4 gallons of gasoline. Another car is red. It can travel 20 4 miles on 5 gallon of gasoline. What is 5 the unit rate for miles per gallon for each car? Which car could travel the greater distance on 1 gallon of gasoline?

Sagot :

EXPLANATION

Let's see the facts:

Blue car:

40 miles ---->

Red car:

20/4 miles ----> 5 gallons

Unit rate formula:

[tex]unit_{\text{ }}\text{rate = }\frac{dis\tan ce\text{ in miles}}{\text{gallons}}[/tex]

For example, suppose that the blue car travels 37 1/2 miles on 1 3/4 gallons of gasoline, the unit rate will be:

[tex]unit_{\text{ }}\text{rate = }\frac{37\frac{1}{2}}{\text{1}\frac{1}{4}}=\frac{150}{70}\text{miles per gallon}[/tex]
