Calculation of Average Speed

To calculate the average speed of the athlete over the entire distance, we can use the formula:

Average Speed = Total Distance / Total Time

In this case, the athlete ran the first half of the distance at a speed of 11 km/h and the second half at a speed of 9 km/h. To find the total distance, we need to know the length of the entire distance. Unfortunately, the length of the distance is not provided in the question. Therefore, we cannot calculate the average speed without this information.

If you have the length of the distance, please provide it, and I will be happy to help you calculate the average speed.
