Speed of moving sidewalk: 0 m/s 10 m/s              
Mia's running speed (on moving sidewalk)
Speed: 0 m/s 10 m/s              
Brandi's running speed
Speed: 0 m/s 10 m/s              

This simulation involves relative velocity in one dimension. It is an out-and-back race between two women. Mia runs on the moving sidewalk, while Brandi runs on the non-moving floor. Under what conditions is the race a tie? Under what conditions does Mia win? Under what conditions does Brandi win?
