You are at a point, A. You now move 3 km south of Point A to Point B. From Point B, you move to Point C, which is 3 km east of Point B. Draw a diagram to show these movements, and use your diagram to find your distance (at Point C) from the starting Point A. With Point C as your reference, what is the displacement of A? (This exercise would best be done on graph paper.)
