  1. ___________________ The graph plots the time in seconds versus the distance rolled for four rolls of a ball. Identify by the marker shape the fastest ball on the graph.
  2. ___________________ Identify by the marker shape the slowest moving ball on the graph.
  3. ___________________ Determine the speed of the ball depicted by the triangle markers on the graph.
  4. ___________________ Determine the speed of the ball depicted by the circle markers on the graph.
  5. ___________________ Using the above speed of the circle markers ball, how far in centimeters would the ball have rolled after 7 seconds?
  6. ___________________ Using the above speed of the circle markers ball, how many seconds for the ball to roll 2400 centimeters?

  1. ___________________ Speedilynn walked 532 meters in nine minutes and 22 seconds. What was her speed in meters per second?
  2. A ball is rolled and generates the time versus distance data plotted by the circles in the graph on the right. What is happening to the speed of the ball as it rolls?
