Q. 19. Toni drives her car 132mi on the highway on 4 gal of gas. At this rate how many miles can she drive on 9 gal of gas? (See Example 2.)
Calculate MPG: Now we have the miles per gallon Toni's car gets. We multiply this number by 9 gallons to find out how many miles she can drive on 9 gallons of gas.So, we take the result from the first step and multiply it by 9.But wait, I didn't actually do the division in the first step. Let's go back and do that.132/4=33 miles per gallon.
Find Total Miles: Now that we know Toni's car gets 33 miles per gallon, we multiply this by 9 gallons to find the total miles she can drive.So, we calculate 33 miles/gallon ×9 gallons.33×9=297 miles.
