how did i get 0

(Figure 1) In this problem you will determine the average velocity of a moving Correct object from the graph of its position (t) as a function of time t. A traveling object might move at different speeds and in different directions during an interval of time, but if we ask at what constant velocity the object would have to travel to achieve the same displacement over the given time interval, that is what we call the Part E object's average velocity. We will use the notation Vave [t1, t2] to V indicate average velocity over the time interval from t, to t2. For instance, Vave 1, 3] is the average velocity over the time interval from Finally, find the average velocity over the whole time interval shown in the graph. t = 1 to t = 3. Express your answer to three significant figures. View Available Hint(s) igure
