In this problem, direction, distance, and speed are addressed by having students develop ways to use time and distance to describe instantaneous and average speed. This problem can be adjusted for students of different ages and math skills. Students compare the average velocities of Olympic sprinters over different distances, and use Olympic records to determine who the fastest person was in 1996.This problem can be adapted to any race, including races run by the students, where the split times are likely to vary over the course of the race. A materials list, teacher background information, safety practices, assessment, and outcomes are provided. This book selection includes the Table of Contents, Preface, Catalog of Problems, Acknowledgments, About the Authors, Image Credits, and Index
