The graph shows how the distance travelled by an object varies with time. Calculate the instantaneous speed of the object at IOS and 30 s. Calculate the average speed for the whole go s of the motion. Why the information on the graph is insufficient to determine the average velocity of the object? 1600 1200 800 Instantaneous speed at IOS Instantaneous speed at IOS Average speed 1600 1200 I Chcose J I Chcose J I Chcose J
