Question

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

Answer 1

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
