Questions asked:

1) What is the average speed of Rich Eisen running the 40 yard dash, in meters per second? What is the average speed of Jacoby Ford (the fast guy with yellow shoes)? What is the average speed of “Mount” Cody (the big guy in green.)

2) How big a head start would Rich Eisen need to tie Jacoby Ford in the race?

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