A car uses 5 gallons of gas for every 120 miles it travels.

how many gallons of gas does the car use if it travels 600 miles.

25 gallons

Step-by-step explanation:

First we want to find out how many times the car passes 120 miles in 600 miles, so we divide:

600 : 120 = 5

You drive 120 miles 5 times within 600 miles.

So, if you use 5 gallons of gas for 120 miles and you drive 120 miles 5 times within 600 miles, you multiply 5 by 5:

5 * 5 = 25

Therefore, you use 25 gallons of gas driving 600 miles.
