t (s): 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
x (s): 0, 5, 20, 45, 80, 90, 100, 100, 100, 100, 80, 60
1. find the greatest speed. I don't know which one it is since there are 4 points of "100"
2. least speed? Do I count "0" or"1"?
3. the speed is constant? would I choose 6, 7, 8,9?
4. average speed of particles for the first 7 s?
5. find the instantaneous speed of the particles at 3s.
Could someone explain all of this to me?
