Question from J, a student: What is the average rate of change of gasoline used, measured in miles per gallons if you travel 212 miles, then you fill your gas tank up again and it takes 10.8 gallons. If you designate your change in distance as 212 miles and your change in gallons as 10.8? |
Hi,
The units tell you what to do. You want the rate of change in miles per gallon or miles/gallons. How many miles did you go? How many gallons of gasoline did you use?
