Gas mileage is the number of miles you can drive on a a gallon of gasoline. a test of a ne cae results 350 miles on 10 gallons of gas. how far could you drive on 70 gallons of gas? what is the cars gas mileage?

The gas mileage is 35 mpg, and the car can drive 2450 miles on 70 gallons

Let x be the distance driven on 70 gallons of gas. Let's use the rule of three:
10 gallons --> 350 miles
70 gallons --> x

x = (70*350)/10 = 2450
So you can drive 2450 miles on 70 gallons of gas.

The gas mileage is the number of miles you can drive on 1 gallon of gasoline, and let y be that distance. Let's use again the rule of three:

70 gallons --> 2450 miles
1 gallon --> y

y = 2450/70 = 35 miles.

So, the gas mileage of the cars is 35 miles/gallon.

Hope this Helps! :)
