Beating Usain Bolt

Beating Usain requires a head start. With a race against Usain Bolt as a background, the resource introduces a system of linear equations. A quick activity uses tables to determine whether a head start is enough for the presenter to win a race against Usain Bolt. The video challenges individuals to determine how much of a head start the presenter needs to come out victorious.
