Answer:
1) 28.4 miles per gallon
2) 34 miles per gallon
3) the silver car
Step-by-step explanation:
We have the following information:
Blue car:
Travels 35 1/2 miles on 1 1/4 gallons of gasoline
Silver car:
Travels 27 1/5 miles on 4/5 gallons of gasoline
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:
Blue car:
(35 1/2) / (1 1/4) = 28.4 miles per gallon
Silver car:
(27 1/5) / (4/5) = 34 miles per gallon
