Lea drove 420 miles and used 20 gallons of gas. How many miles per gallon did her car get? *my question is what would be the equation so I can solve it?

420/20 = mpg

Thanks

You're welcome.

To find the miles per gallon (MPG) Lea's car got, you can use the equation:

MPG = Total miles driven / Total gallons of gas used

In this case, the total miles driven is given as 420 miles and the total gallons of gas used is given as 20 gallons. Plugging in these values into the equation, you get:

MPG = 420 miles / 20 gallons

Now, you can simply divide the total miles driven (420 miles) by the total gallons of gas used (20 gallons) to find the MPG:

MPG = 21 miles per gallon

Therefore, Lea's car got 21 miles per gallon.
