Answer 1

Step-by-step explanation:

BLue car:

45 1/2 miles consumes 1 1/4 gallons of gasoline

The unit rate = number of miles/number of gallons used

Unit rate in miles per gallon = (45 1/2)/(1 1/4)

`\begin{gathered} \text{unit rate = }(91)/(2)/(5)/(4) \\ =(91)/(2)*(5)/(4)=(455)/(8) \\ \text{unit rate = 56.875 miles per gallons} \\ \text{unit rate = 56 7/8 miles per gallon} \end{gathered}`

Red car:

23 1/5 miles consumes 4/5 gallon of gasoline

Unit rate = (23 1/5)/(4/5)

`\begin{gathered} \text{unit rate = }(116)/(5)/(4)/(5)=(116)/(5)*(5)/(4) \\ \text{unit rate = }(116)/(4) \\ \text{unit rate = 29 miles per gallons} \end{gathered}`
