Help with average speed/instantaneous speed! :( 1. The problem statement, all variables and given/known data 1. EDIT: Figured this one out, now I just need to know about the 2nd question about instantaneous speed. 2. What is its instantaneous speed at t = 20 s? 2. Relevant equations v= change in x/change in t 3. The attempt at a solution I have no idea how to do this. My textbook doesn't really cover this section well, and I'm just starting out in Physics. I did v=2/20 and came out with .1, but I think it's wrong.
