Answer: 270.9 miles.
Step-by-step explanation:
The formula we use here is :
[tex]\text{Distance=Speed * Number of gallons of gasoline}[/tex]
Given : Ashton used 12.6 gallons of gasoline to drive his car on a weekend trip. he averaged 21.5 miles per gallon.
Then [tex]\text{Distance traveled }=12.6\times21.5=270.9\text{ miles}[/tex]
Hence, he traveled 270.9 miles.
