Question

Suppose that the distance a car travels varies directly with the amount of gasoline it uses. a certain car uses 11 gallons of gasoline to travel 198 miles. how many miles can the car travel if it has 10 gallons of gasoline?

Answer 1

The easiest way to solve this problem is to first find how many miles you can travel with 1 gallon. To do this you divide 198 miles by 11 gallons. With this you can determine that 1 gallon gets you 18 miles. Multiply 18 by 10 and you get 180. 10 gallons lets you travel 180 miles.
