speed does not care about direction... you did that part correctly in the first 3 seconds you moved 3 meters the next 3 seconds you did not move in the last 3 seconds you moved 2 meters total distance traveled is 5 meters over 9 seconds or 5/9 m/s

velocity is the distance between the starting point and the ending point divided by the time. you start at x=0 and end up at x=1 over the course of 9 seconds velocity is 1/9 m/s

(a) is correct for (b) i am not sure only guess work. 1.may be but not sure, displacement in 9 seconds=3-2=1 m only. average velocity=1/9m/s
