Final answer:
Edson is running at a speed of approximately 4.38645 meters per second.
Step-by-step explanation:
To calculate the speed at which Edson is running, we need to divide the distance he runs by the time it takes. In this case, Edson runs 43.2 yards in 9 seconds. To convert yards to meters, we multiply the distance by 0.9144 (since 1 yard is approximately 0.9144 meters). So, 43.2 yards is approximately 39.47808 meters. Now, to calculate the speed, we divide the distance (in meters) by the time (in seconds):
Speed = Distance / Time
Speed = 39.47808 meters / 9 seconds
Speed ≈ 4.38645 meters per second
Therefore, Edson is running at a speed of approximately 4.38645 meters per second.
