Jeffree Star starts driving his hot pink Tesla South at a speed of 10m/s. Realizing he forgot his dog Davinci at home, Jeffree turns around going northbound and reaches a speed of 20 m/s at 20 seconds. What is Jeffree’s average acceleration?

---------------------------
find the slope of the secant line
points: (0, -10) and (20,20)
(20+10)/(20-0) = 30/20
Jeffree's average acceleration is 30/20 m/s^2 or 3/2 m/s^2.

Problem:Anna is following the position vs. time graph. What is Anna's velocity from 1 seconds to 4 seconds.

------------------------------
Solution:  Anna's velocity is 0 m/s.
Work
Step 1: Label the points (1,3) (4,3)
Step 2: Find the slope using the points. ((3-3)/(4-1))= (0/3) = 0
Step 3:Write the answer in a sentence.

Michelle Obama decided to take Bo for a walk. She traveled according to a position vs. time graph.
(a) Find Michelle's Average speed.
(b) Find Michelle's average velocity.
----------------------------------
Answers:
(a) Find Michelle's average speed.
6+0+6/ 8 = 12/8 = 3/2 m/sec
Michelle's average speed was 3/2 m/s.

(b) Find Michelle's average velocity.
0/8 = 0 m/sec
Michelle's average velocity was 0 m/sec.
