Answer:
Brooke runs the fastest.
Step-by-step explanation:
Brooke runs 13 feet per second.
Therefore, speed of Broke = 13 feet per sec.
Will runs 308 feet in 26 seconds.
Speed of Will = 
= 
= 11.85 feet per second
Ron runs 1 mile in 551 seconds.
1 mile = 5280 feet
Speed of Ron = 
= 9.58 feet per second
Debbie runs 658 feet in 1 minute.
1 minute = 60 seconds
Speed of Debbie =
= 10.97 feet per seconds
Here, speed of Brooke is the maximum.
Therefore, Brooke runs the fastest.
If you would like to know which pair of measurements is not equivalent, you can calculate this using the following steps:
1 yard = 3 feet
1 foot = 12 inches
1 mile = 5280 feet
8 yards = 8 * 3 feet = 24 feet
2 feet = 2 * 12 inches = 24 inches
10 feet = 10 * 12 inches = 120 inches
3 miles = 3 * 5280 feet = 15,840 feet
Not equivalent: <span>3 miles, 15,480 feet.</span>
Hope this helps!!! It's how I found it I hope it's right
