A car can travel 105 miles on 7 gallons of gas. How far can it travel on 9 gallons

Find how far the car can travel on one gallon of gas, by dividing total miles by number of gallons:

105 miles / 7 gallons = 15 miles per gallon.

Now multiply that by the number of gallons to find total miles:

15 miles per gallon x 9 gallons = 135 total miles.
