Example Carol is jogging at constant velocity. Below is the displacement-time graph for the first 10 s of her jog.

The area under a curve can be estimated by dividing it into triangles, rectangles and trapeziums. If we have a speed-time or velocity-time graph, the distance travelled can be estimated by finding ...
