Answer:
<u><em>Stephanie runs the fastest per second: 14 feet per second</em></u>
Step-by-step explanation:
To find the fastest speed, you need to see which person runs the most per second:
Stephanie runs <em>14 feet per second</em>
<em />
Brooke runs 589 feet in 44 seconds.
Find the amount of feet per second by dividing:
Brooke runs about <em>13.4 feet per second</em>
<em />
Will runs 1 mile in 454 seconds.
Convert the miles to feet:
There are 5,280 feet in a mile. If Will runs 5,280 feet in 454 seconds, divide to find how much he runs per second:
Will runs about <em>11.6 feet per second.</em>
<em />
Rob runs 548 feet in a minute.
Convert the minute into seconds. There are 60 seconds in a minute. Divide the feet by the seconds to find how fast he runs per second:
Rob runs about <em>9.1 feet per second.</em>
Stephanie runs 14 feet per second, the fastest time:
| 14 |, 13.4, 11.6, 9.1
<em>Finito.</em>
