In 1912, the world record for running 3000 meters was 8 minutes and 36.8 seconds. What was the runner's average speed?

Answer :

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.
