Final answer:
The runner's average speed is 5.81 meters per second.
Explanation:
To calculate the runner's average speed, we need to convert the time taken to seconds. Since there are 60 seconds in a minute, 8 minutes is equal to 8*60 = 480 seconds. The total time is therefore 480 + 36.8 = 516.8 seconds. Now, we can divide the distance of 3000 meters by the time to find the average speed.
The average speed is given by:
Average Speed = Distance/Time = 3000 meters / 516.8 seconds.
Calculating this gives us an average speed of 5.81 meters per second.
