Calculate the speed of the car at each checkpoint by dividing the distance between each checkpoint in meters by the change in time. Record your answers in Table C of your Student Guide.

The speed at the first quarter checkpoint is 0.74 m/s.

The speed at the second quarter checkpoint is 1.40 m/s.

The speed at the third quarter checkpoint is 1.61 m/s.

The speed at the finish line is 1.89 m/s.
