Green Graphing

Create and interpret line graphs to find out which cars are friendliest to the environment.
- Read what "Green Score" means.
- Click best, which is in the first paragraph. Select one car. Write down the make and model. Record the gas mileage listed in the column under "MPG: City."
- Click the Back arrow.
- Click worst. Select one car. Write down its make and model. Record the gas mileage listed under "MPG: City."
- Use these figures to complete your activity.
- The term “miles per gallon (MPG)” refers to the number of miles that a vehicle can travel on one gallon of gas. Make a line graph for one car from the Best list, showing the average MPG that the car gets in the city. Label the vertical axis "Miles That Can Be Traveled" and mark the axis in units of ten starting at 0. Label the horizontal axis "Gallons of Gas" and mark that axis in units of one from 0 to 6. Title the graph "Gas Mileage for ." (Fill in the name of the car you chose.)
- Make a line graph for one car from the Worst list showing the average MPG that the car gets in the city. Label the vertical axis "Miles That Can Be Traveled" and mark the axis in units of ten from 0 to 100. Label the horizontal axis "Gallons of Gas" and mark that axis in units of one from 0 to 6. Title the graph "Gas Mileage for ." (Fill in the name of the car you chose.)
Use the numbers in the line graphs and in the text to answer the questions.
- For each line graph, write an equation to represent the function. Let t = total miles that can be traveled. Let g = gallons of gas.
- Look at your graphs. Describe the relationship between miles that can be traveled and gallons of gas used.
- How many miles can you travel in the Best car using 3 gallons of gas? How many miles can you travel in the Worst car using 3 gallons of gas? How many more miles can you travel in the Best car than in the Worst car?
- How many gallons of gas would you need to travel 150 miles in the Best car? In the Worst car? How many more gallons of gas would you need for the Worst car than for the Best car? Round your answers to the nearest tenth of a gallon.
- If gas costs $1.75 per gallon, how much would it cost you to drive 70 miles in the Best car? In the Worst car? What is the difference in cost? Which car would you use and why?

Today I explored a Web site that evaluates different types of cars to compare how environmentally friendly they are. I worked with statistics showing the average number of miles that each car can travel on one gallon of gas. I created line graphs using this data, and interpreted the information in the graphs. I figured out that the can travel miles on 3 gallons of gas!
You can find out more about this topic by asking your teacher or parents to show you other Web sites.
