Answer:
The formula to calculate average speed is:
average speed = total distance / total time
In this case, the distance covered is 500 meters and the time taken is 14.5 minutes. However, we need to convert the time to seconds to get the answer in meters per second.
14.5 minutes = 14.5 x 60 seconds = 870 seconds
So, the average speed is:
average speed = total distance / total time
average speed = 500 meters / 870 seconds
average speed = 0.57 meters per second
Therefore, the average speed of the runner is 0.57 meters per second.
