显示的时间是沿着x轴的箴言ided graph. Between theand theperiod of the race, the driver is goingat each time point. We can see from the straight line between those two points that the race car driver's speed doesn't change; thus, the race car driver is driving at a consistent speed.

显示的时间是沿着x轴的箴言ided graph. During the lastof the race, the driver goes from, displayed on the y-axis of the graph, to. We can see the line between those two points is decreasing in a negative direction, or getting slower; thus, the race car driver is decreasing his speed.

显示的时间是沿着x轴的箴言ided graph. During the firstof the race, the driver goes from, displayed on the y-axis of the graph, to. We can see the line between those two points is increasing in a positive direction, or getting faster; thus, the race car driver is increasing his speed.

When the time is at, displayed along the x-axis, we see that the speed, displayed along the y-axis is also. If a car has a speed of, the car is not moving. And if the time is at, the race has not started; thus, the race car driver is waiting to begin the race.

Between theandpart of the race, the race car driver decreases his speed fromto. If we look pasted this point on the graph, we see that he speeds back up and continue with the race, so the race didn't not end. He also didn't stop, because his speed never hit; thus, he must have had to slow down for some reason, but then resumed the race.
