  1. _______________ Determine the speed of marble A.
  2. _______________ Determine the speed of marble B.
  3. _______________ Determine the speed of marble C.
  4. _______________ Determine the speed of marble D.

    The next four questions are matching. The second graph depicts the time versus distance data for four different marbles. One marble was not moving, one marble was slowing down, one marble was speeding up, and one was moving at a constant speed. Use the letters E, F, G, and H at the end of the lines on the xy scattergraph to match the correct line to the marble behavior.
