# Twice as Fast

Now create a new race by changing the speed, distance, and time.

Decide on the track you want and the distance of the track. Then set up the race so that Racer 1 goes twice as fast as Racer 2 and Racer 2 goes twice as fast as Racer 3.

- Sketch a graph to predict what the graph of the race will look like, then start the race.
- Compare your graph with the race graph in the interactive.
- Explain your thinking in setting up the race and your prediction as compared with the results.
