Mikes car gets an average of 28 mpg. there are 12 gallons of fuel in mikes car when he starts his trip of 140 miles. about how many gallons are left at the end of his trip?

7 gallons are left.
Since he goes 28 miles per gallon and he drives 140 miles, you divide 140 by 28 and get 5 (number of gallons he used) and subtract that number by the total number of gallons of fuel he had at the start of his trip giving you 7 gallons left. Hoped this helped
