#18 \ "miles/gallon"#

Just divide the total miles traveled by the total number of gallons consumed.

#(90 \ "miles")/(5 \ "gallons")#

#=18 \ "miles/gallon"#

To find the rate in miles per gallon, divide the number of miles by the number of gallons. So, 90 miles divided by 5 gallons equals 18 miles per gallon.
