A girl walks along a straight path to drop a letter in the letterbox and comes back to her initial position. Her displacement-time graph is shown in the figure. Plot a velocity-time graph for the same.

From the given distance-time graph, 



$=2\ m/s$

In the given distance-time graph the symmetry indicates that the girl reaches back to her initial position with the same velocity$(2\ m/s)$ but in opposite direction. So, the velocity-time graph will be as below:
