Given the speeds of each runner below, determine who runs the fastest.
Jessica runs 13 feet per second.
Stephanie runs 439 feet in 36 seconds.
Debbie runs 1 mile in 497 seconds.
Noah runs 546 feet in 1 minute.
To determine who runs the fastest, we need to compare the speeds of each runner.
First, we need to convert Stephanie's distance and time to feet per second.
Stephanie runs 439 feet in 36 seconds, so her speed is 439 feet / 36 seconds = 12.19 feet per second.
Next, we need to convert Debbie's distance and time to feet per second.
Since 1 mile is equal to 5280 feet and 1 minute is equal to 60 seconds, Debbie's speed is 5280 feet / 497 seconds = 10.64 feet per second.
Lastly, we need to convert Noah's distance and time to feet per second.
Noah runs 546 feet in 1 minute, so his speed is 546 feet / 60 seconds = 9.1 feet per second.
Comparing the speeds of each runner:
- Jessica runs 13 feet per second.
- Stephanie runs 12.19 feet per second.
- Debbie runs 10.64 feet per second.
- Noah runs 9.1 feet per second.
Therefore, Jessica runs the fastest with a speed of 13 feet per second.
