Represent the Situation Mathematically

Now that you have used some easy numbers to represent the situation, it's important to make a general representation of the situation that will work for any numbers.

  • Make a ratio table showing the relationship between time and distance.
  • How could you use your completed ratio table to make a graph?
  • Write a formula that shows the relationship between time and distance.
  • Make a graph of this formula. How would you label the x-axis (independent variable) and the y-axis (dependent variable)?
  • Make a graph of the formula for distances up to 20 miles.

Hint:

Use the pairs of numbers in your ratio table as points on your graph.
