Answer: Stephanie is the fastest
Step-by-step explanation:
Here we have to find who runs faster:
Liz:
[tex]8 ft/s[/tex]
Katie:
[tex]\frac{350 ft}{31 s}=11.29 ft/s[/tex]
Stephanie:
[tex]\frac{1 mile}{388 s}. \frac{5280 ft}{1 mile}=\frac{5280 ft}{388 s}=13.60 ft/s[/tex]
Noah:
[tex]\frac{541 ft}{1 min}. \frac{1 min}{60 s}=9.01 ft/s[/tex]
As we can see after comparing, Stephanie is the fastest, since she travels more distance in less time.
