After yesterday working with our variable speed cars to find average speed and instantaneous (fastest) speed:
We took that experience to start writing our own problems based on speed, average speed, and average velocity:
Students had parameters of 5 steps, one negative step, and non-zero displacement. They then developed the scenario and found the speed of each leg, average speed of the journey, total displacement, average velocity, which they will give to another group to solve next class.
