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 s

VikaD [51]

Answer: Stephanie is the fastest

Step-by-step explanation:

Here we have to find who runs faster:

Liz:

$8 ft/s$

Katie:

$\frac{350 ft}{31 s}=11.29 ft/s$

Stephanie:

$\frac{1 mile}{388 s}. \frac{5280 ft}{1 mile}=\frac{5280 ft}{388 s}=13.60 ft/s$

Noah:

$\frac{541 ft}{1 min}. \frac{1 min}{60 s}=9.01 ft/s$

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

a cellular telephone tower casts a shadow that is 72 feet long. while a nearby tree that is 27 feet tall casts a shadow that is

timurjin [86]

Shadow length is proportional to object height.
(tower height)/(tower shadow length) = (tree height)/(tree shadow length)
(tower height)/(72 ft) = (27 ft)/(6 ft)
(tower height) = (72 ft)*(27/6)
(tower height) = 324 ft

The cellular telephone tower is 324 ft tall.
