You are running a fuel economy study. One of the cars you find is blue. It can travel 28 miles on131gallon of gasoline. What is4gallons of gasoline. Another car is red. It can travel 21 5 miles on5the unit rate for miles per gallon for each car? Which car could travel the greater distance on 1 gallonof gasoline?

Question 2

$\begin{gathered} Blue\text{ car} \\ Dis\tan ce=28(1)/(2)miles=28.5miles \\ Gasoline\text{ = }1(1)/(4)gallons=1.25gallons \\ \text{rate}=(28.5miles)/(1.25gallons)=(114)/(5)\text{miles per gallon=22.8 miles per gallon} \\ \text{rate}=22.8\text{ miles per gallon} \\ \operatorname{Re}d\text{ Car} \\ Dis\tan ce=21(3)/(5)miles=21.6miles \\ Gasoline\text{ =}(4)/(5)gallons=0.8gallons \\ \text{rate}=(21.6miles)/(0.8gallons) \\ \text{rate}=27\text{ miles per gallon} \\ \text{The car red could travel }greater\text{ distance.} \\ The\text{ unit rate }for\text{ the blue car is }(114)/(5)\text{miles per gallon} \end{gathered}$
