The 2011 Indianapolis 500 had an unexpected ending. This activity provides students with information about the last lap of the top three finishers, including their position relative to one another when the last lap started and their approximate speeds at various times during the last lap. Students can work in groups and use their understanding of integration to predict in which order the cars finish. A link is included to show them the footage of the last lap of the race once they have made their predictions. This activity allows students to review and apply integration skills such as left/right Riemann sums, trapezoidal approximations, net change, and definite integration, while challenging them to think critically and providing a fun classroom experience.
