Use the average speed - distance - time relationship and unit conversion methods to answer the following questions:

1. What is the average speed of Rich Eisen running the 40 yard dash, in meters per second?

2. What is the average speed of Jacoby Ford (the fast guy with yellow shoes), in meters per second?

3. What is the average speed of Terrence “Mount” Cody (the big guy in green), in meters per second?

4. If Rich Eisen and “Mount” Cody ran a 100-meter long race, who would win and by how much of a distance? (You may assume that they run the 100-meter race with the same average speed that they ran the 40-yard dash.)

Was the assumption you made answering question #4 a "good" assumption to make? Why or why not?
