Final answer:
The average speed is calculated by dividing the distance by the time. Without the time taken for the 25-meter course, we can't determine the fastest average speed of a student. An example of calculating such a speed would involve using the provided formula with actual time data.
Step-by-step explanation:
To determine the fastest average speed of the student who ran the 25-meter course, we must have specific information about that student's time. Without the student's time, we cannot calculate their average speed. However, we can discuss the concept of average speed in general. Average speed is defined as the total distance traveled divided by the total time taken to travel that distance.
If we look at Usain Bolt's world record, we have a clear example. He ran 100 meters in 9.58 seconds, which gave him an average speed of 10.4 meters per second (m/s), or approximately 23.4 miles per hour (mph). To find the fastest average speed for a 25-meter distance, we'd use the formula:
average speed = total distance / total time
Assuming we had a time of 3 seconds for a 25-meter course, the calculation for average speed would be:
average speed = 25 meters / 3 seconds = 8.33 m/s
This is merely an example, as the exact time taken by the fastest student for the 25-meter course is not provided.
