Since not enough time was spent last time on speed-time graphs, we focus on that part today to make sure students get a good understanding of how to read a speed-time graph, how to calculate the distance, how to draw a distance-time graph from a speed-graph, etc.

There are some homework that is about speed-time graph, please use last class’s homework sheets and do or redo the parts about speed-time graph.

We will have a quick review of statistics and probabilities next time. We will have our final exam on 6/18.

Here are some more homework:
