A runner completes a race in 10 seconds. If she consistently runs 100 meters, what is her average speed?

To determine the average speed of the runner, you use the formula for average speed, which is the total distance divided by the total time taken. In this case, the runner completes a distance of 100 meters in a time of 10 seconds.

Calculating the average speed involves dividing the distance by the time:

Average speed = Total distance / Total time

Average speed = 100 meters / 10 seconds = 10 m/s

This calculation reveals that the runner maintains a consistent pace of 10 meters per second throughout the race, making the answer accurately reflect her speed over the entire distance covered. Understanding this formula and its application is crucial for interpreting average speed in similar scenarios.
