A car is driven 402.5 miles on 11.5 gallons of gas. Find the number of miles traveled per gallon of gas

I believe it's 35 miles per gallon of gas

35 miles per gallon

Step-by-step explanation:

Here we know that the car driven 402.5 miles on 11.5 gallons of gas, so we can write the following equivalence:

402.5 m = 11.5 g

With m being miles and g gallons.

We want to know the equivalent of miles for 1 gallon. So, lets take the equivalence and divide it by 11.5

402.5/11.5 m = 11.5/11.5 g

35 m = 1g

So, each gallon permits to travel 35 miles. If you want to verify it, just multiply 11.5 (the gallons) g by the number of miles, 35:

11.5 * 35 = 402.5
