1.If my car gets 26 miles to the gallon and the tank can hold 13.2 gallons of gas, how many miles can I travel?

343.2 miles

Explanation:

To find the miles that you can travel with 13.2 gallons of gas, you can use a rule of three given that you know that the car gets 26 miles to the gallon:

    1 gallon   →   26 miles

13.2 gallons →        x

x=(13.2*26)/1

x= 343.2

According to this, the answer is that you can travel 343.2 miles.

consider the reaction below.
