Driving to the Park

Look at the table you completed in the last lesson that shows the relationship between the time Mr. Lee drove and the distance he traveled.

  • Is there a constant of proportionality? If not, explain why not.
  • If so, give the values of both constants of proportionality.
  • If this is a proportional relationship, use one of the values to write a formula that represents the proportional relationship between time and distance traveled.
