Position Time Graphs-Average Speed 1⁰
In the position vs. time graphs below, all the times are in seconds (s), and all the positions are in
meters (m).
Rank these graphs on the basis of which graph indicates the greatest average speed, where the
average speed is calculated from the beginning to the end of motion. Give the highest rank to
the one(s) with the greatest average speed, and give the lowest rank to the one(s) indicating the
least average speed.

Or, none of these are moving at all.
Or, the average speed is the same for all of these.
Please carefully explain your reasoning.
