Final answer:

To determine who runs the fastest, compare the speeds of each runner. Brooke runs the fastest at a speed of 11.983 feet per second.

Step-by-step explanation:

To determine who runs the fastest, we need to compare the speeds of each runner. Let's convert all the speeds to the same unit for easier comparison.

  • Will runs at a speed of 15 feet per second.
  • Stephanie runs 118 feet in 11 seconds, so her speed is 118/11 = 10.727 feet per second.
  • Frank runs 1 mile in 530 seconds, which is 5280 feet, so his speed is 5280/530 = 9.962 feet per second.
  • Brooke runs 719 feet in 1 minute, which is 719/60 = 11.983 feet per second.

Comparing the speeds, we see that Brooke runs the fastest at a speed of 11.983 feet per second.
