Cecil averages 31 miles per gallon when driving his car on the highway to visit friends 461 miles away.If he filled the 16-gallon gasoline tank before leaving and did not buy any gasoline along the way, about how many gallons of gasoline are left in the tank when he arrives?

Update:

Cindy, how could the answer be 35 when the person had started with only 16 gallons?

Multiply 31 by 16 to see how many miles he can get with his full tank. (this comes out to be 496).

Subtract 461 away from 496 and that is how many gallons of gasoline are left in the tank when he arrives.

Which is 35

No of gallons consumed = 461/31 = 14.87 gallons

Gallons remaining = 16 - 14.87 = 1.13 gallons ANSWER
