A car has a 16 gallon fuel tank when driving on a highway it has a gas milage of 30 miles per gallon how many miles has a car traveled if it has 2.5 gallons of gas left in the tank

So to make this easier let’s just subtract 13 from the 16 gallons, and in turn multiply 30*13=390. Now after that we just divide 30/2 or multiply 30*.5 which gives us 15 adding that to the total 390+15=405. So the answer would be “The car has traveled 405 miles.”
