Question

Liz runs 8 feet per second. Katie runs 350 feet in 31 seconds. Katie runs 350 feet in 31 seconds. Stephanie runs 1 mile in 388 seconds. Stephanie runs 1 mile in 388 seconds. Noah runs 541 feet in 1 minute. Noah runs 541 feet in 1 minute.

Answer 1

Answer: Stephanie is the fastest

Explanation:

Here we have to find who runs faster:

Liz:

`8 ft/s`

Katie:

`(350 ft)/(31 s)=11.29 ft/s`

Stephanie:

`(1 mile)/(388 s). (5280 ft)/(1 mile)=(5280 ft)/(388 s)=13.60 ft/s`

Noah:

`(541 ft)/(1 min). (1 min)/(60 s)=9.01 ft/s`

As we can see after comparing, Stephanie is the fastest, since she travels more distance in less time.
