Go to http://threeacts.mrmeyer.com/playingcatchup/ to watch the video of Rich Eisen and Julio Jones running the 40-yard dash. Use the formula D=rt where D is distance, r is rate, and t is time.

1. Solve D=rt for rate. (1 pt)

1. Use the statistics given in Act Two and your equation from #1.
2. At what speed (rate) does Rich run the 40-yard dash?

1. At what speed (rate) does Julio run the 40-yard dash?

1. Solve D=rt for time. How long does it take Rich to run with a 10-yard lead?

How long does it take Julio to run the 40-yard dash at half-speed? Who will win?

3. If both runners are at full speed, how many yards of a head start will Rich need to win?

4. Write and solve your own question using this scenario.
