Set Pikachu's and Charmander's start locations with the sliders. Click on Pikachu to put him at his start location. Click on Charmander to put him at his start location. Figure out combinations of Pikachu's Speed, Charmander's Speed, and the number of seconds that will make Pikachu and Charmander meet and stop in exactly the same place. Speed is in steps per second. Click on the green flag whenever you want to see them go.
In this project, Liam challenges the user (the gamer) to find combinations that will cause Pikachu and Charmander to meet and stop in exactly the same place. Liam's never heard of systems of equations -- but he's using them.
