the elevator pitch math quiz
question 9 of 10: you are in a 98 - story building taking the elevator to the top from the bottom. each story is 15 feet. the elevator travels at 29.33 feet per second. how long do you have for your elevator pitch?
a) 10 seconds
b) 50 seconds
c) 300 seconds

Explanation:

Step1: Calculate total height

The building has 98 stories and each story is 15 feet. So the total height $h$ of the building is the number of stories times the height per - story.
$h = 98\times15=1470$ feet

Step2: Calculate time

The speed of the elevator $v = 29.33$ feet per second. We know that speed $v=\frac{d}{t}$, where $d$ is distance and $t$ is time. Rearranging for time $t=\frac{d}{v}$. Here, $d = h = 1470$ feet and $v = 29.33$ feet per second.
$t=\frac{1470}{29.33}\approx50$ seconds

Answer:

B. 50 seconds
