Answer:

Step-by-step explanation:

Usain Bolt

Part A

d = 200 m

t = 19.30 seconds

r = d/t

r = 200 / 19.30

r = 10. 36

r = 10.4 m/s

Part B

d = 400 meters

t = 43.18 seconds

r = d/t

r = 400/43.18

r = 9.26 m/s

r = 9.3

Not much difference.

Michael Johnson

Though you have not given us the distance, it was 100 meters. He was the first man to eclipse 9.7 seconds for the 100 meters.

d = 100 m

t = 9.69 seconds

r = 100 meters/9.69 seconds

r = 10.32 m/s

r = 10.3
