Answer:
[tex]30\ miles\ per\ gallon[/tex]
Step-by-step explanation:
we know that
To find out the unit rate divide the total miles by the total gallons
Let
x ----> the number of miles
y ----> the number of gallons
[tex]unit\ rate=\frac{x}{y}[/tex]
we have
[tex]x=30\ miles\\y=1\ gallon[/tex]
substitute
[tex]\frac{30}{1}=30\ miles\ per\ gallon[/tex]
