Gas mileage is the number of miles you can drive on a gallon of gasoline. a test of a new car results in 600 miles on 20 gallons of gas. how far could you drive on a 70 gallons of gallons? what is the cars gas mileage

Ok for this we need to create something that I think is really cool in math!

Always write what you know first! Ask yourself what do you know? Well, you know that a car can run 600 miles on 20 gallons.

So set up a "fraction" which is actually a ratio that looks like this: 600/20

Ok, now we need to know how many miles 70 gallons will last

So set up another ratio that looks like this: x/70

X stands for the amount of miles

Now you use cross products to solve!

You should get: 2,100 miles

Comment if you have questions! Glad to help!
