Use the formula D=rt where D is distance, r is rate, and t is time.
1. Solve D=rt for rate. (1 pt)
40
2. Use the statistics given in Act Two and your equation from #1.
a. At what speed (rate) does Rich run the 40-yard dash? (1 pt)
b. At what speed (rate) does Julio run the 40-yard dash? (1 pt)
c. Solve D=rt for time. How long does it take Rich to run with a 10-yard lead? (1 pt)
D=30 yds
d. How long does it take Julio to run the 40-yard dash at half-speed? Who will win? (2 pts)
3. If both runners are at full speed, how many yards of a head start will Rich need to win? (2 pts)
4. Write and solve your own question using this scenario. (Remember to show all work!) (2 pts)
