Study the graph shown below. It is a graph of velocity vs. time for Kiera when she is riding her bicycle.

Graph of velocity vs. time with time on the x axis from 0 to 10 seconds and velocity on the y axis from 0 to 5 m per s. Segment 1 goes from 0.0 to 2,3. Segment 2 goes from 2,3 to 4, 3. Segment 3 goes from 4,3 to 5,2. Segment 4 goes from 5,2 to 6,2. Segment 5 goes from 6,2 to 7,4. Segment 6 goes from 7,4 to 8,4. Segment 7 goes from 8,4 to 9,0.
