how many miles would a car with a 13 gallon tank have traveled if it has 10 gallons left?

Answer 1

13 gallon tank with 10 gallons left

means it drove 3 gallons times mpg

if it got 20 mpg, then it drove 3x20 = 60 miles

if it got 30 mpg then it drove 3x30 = 90 miles

if it traveled in city stop & go traffic, it's harder to calculate

but call it 15 mpg and 3x15 = 45 miles
