Final answer:

Debbie runs the fastest.

Step-by-step explanation:

To determine who runs the fastest, we need to compare the speeds of Jessica, Will, Katie, and Debbie. Let's convert their speeds to a common unit for easier comparison.

Jessica runs 12 feet per second. Will runs 203 feet in 23 seconds. Katie runs 1 mile in 379 seconds. Debbie runs 681 feet in 1 minute, which is equal to 60 seconds.

Converting Katie's time to feet per second, we divide the distance by the time: 1 mile = 5280 feet, 379 seconds = 5280 feet / 379 seconds = 13.93 feet per second.

Comparing the speeds, Debbie runs the fastest with a speed of 681 feet per minute, which is equivalent to 11.35 feet per second. Therefore, Debbie runs the fastest.

Complete question is:

Given the speeds of each runner below, determine who runs the fastest. Jessica runs 12 feet per second. Will runs 203 feet in 23 seconds. Katie runs 1 mile in 379 seconds. Debbie runs 681 feet in 1 minute.
