VIDEO 2: Distance versus time. Watch by Tuesday, August 28 (the parts mentioned below)
https://www.youtube.com/watch?v=NeIVKPjXFGE
This is a ten minute video, but I'm mainly interested in the part FROM 0:45 TO 2:45! (So I'm assigning that time interval, if you don't want to watch all ten minutes) The narrator is very silly, but the math is sound, and it will help you to understand some of the subtleties we are talking about in class. There will be a question about it on your homework.
