Perfect ACT Scorer (36) with Math Knowledge up to Multivariable Calc

In this case, we would calculate rate by dividing the distance travelled by the amount of gas needed to travel that distance. So since we were able to cover 230 miles using 10 gallons of gas, that means each gallon of gas gets us 230/10 = 23 miles of travel.

We can check our work by saying "well, if each gallon of gas gives me 23 miles, then how many miles does ten gallons of gas give me?" So you multiply 23 by 10, and you get 230, which is the original amount of miles you travelled!
