 * Student Name:** Linda Fahlberg

Statement of Problem: I drive 5 hours at 30mph.
What do I need to do: Use the Rule of Four to completely describe this problem. Questions: Solve each using your rule and your GeoGebra worksheet.
 * 1) How far have I driven after 2hours and 30 minutes?
 * 2) How long does it take me to drive 100 miles?
 * 3) I drive 30 minutes and then I look at my odometer. I drive another 75 miles? In total how long and how far have I driven?

Solution: ** Rule 1: Description of variables with units, domain of x, rule for y **
Let x= number of hours Then x can have values: [0,5] Let y= distance in miles Then the relationship of x and y is: y=30*x

Rules 2-4: **GeoGebra worksheet with Algebra - Graph - Table** media type="custom" key="6432777"
