Jessica ran on the track team at her school. She finished the 200-meter race in 54 seconds. What was jessica's average speed, in meters per second, for the 200-meter race?

Where x represent the distance and t the time if we replace the info given we got:

Then the average speed for this case in m/s is 3.704 for the 200 meter race

Step-by-step explanation:

The problem provides for this case the amount of distance travelled by Jessica in a given time. And we know that travels 200m in 54 seconds.

We want to find the average speed and we can use the following formula:

Where x represent the distance and t the time if we replace the info given we got:

Then the average speed for this case in m/s is 3.704 for the 200 meter race
