Answer:
1) 28.4 miles per gallon
2) 34 miles per gallon
3) the red car
Step-by-step explanation:
We have the following information:
<em>Travels 35 1/2 miles on 1 1/4 gallons of gasoline</em>
<em>Travels 27 1/5 miles on 4/5 gallons of gasoline</em>
<em />
We want to know the unit rate for miles per hour, and to do it we have to divide the miles they travel by the gallons each car uses:
(35 1/2) / (1 1/4) = 28.4 miles per gallon
(27 1/5) / (4/5) = 34 miles per gallon
The red car travels greater distance with 1 gallon of gasoline
