Jessica runs 1 mile in 440 seconds.
Ron runs 547 feet in 1 minute.

Debbie
Stephanie
Jessica
Ron

Answer 1

Stephanie runs the fastest with a speed of 13.1 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, feet per second, for an easier comparison:

1. Debbie runs at a speed of 10 feet per second.
2. Stephanie runs a distance of 131 feet in 10 seconds, so her speed is 131 feet / 10 seconds = 13.1 feet per second.
3. Jessica runs 1 mile in 440 seconds. Since there are 5280 feet in a mile, her speed is 5280 feet / 440 seconds = 12 feet per second (approximately).
4. Ron runs 547 feet in 1 minute, which is equivalent to 60 seconds. So Ron's speed is 547 feet / 60 seconds = 9.1 feet per second (approximately).

From these calculations, we can see that Stephanie runs the fastest with a speed of 13.1 feet per second.
