Final answer:
The fastest runner's average speed was 0.63 meters per second after completing 500 meters in 13.2 minutes.
Step-by-step explanation:
The question asks for the average speed of the fastest runner in the Houston Marathon who ran 500 meters in 13.2 minutes. To find the average speed, you need to divide the distance by the time taken.
Given the distance is 500 meters and the time is 13.2 minutes, we must first convert 13.2 minutes to seconds (since speed is usually expressed in meters per second), which gives us 13.2 minutes × 60 = 792 seconds.
Then, the average speed (v) is computed using the formula v = distance/time, which gives us v = 500 meters / 792 seconds = 0.63 meters per second.
