Question

The worlds fastest passenger elevator operates at an average speed of about 10 m/s. If the 60th floor is 219 meters above the 1st floor, how much time does it take the elevator to go from the first floor to the 60th? show work

Answer 1

It takes 21.9 s to get to the 60th floor.

Explanation:

Given

V= 10m/s

time =?

Δ distance = 219m

Speed = distance traveled/time interval

v= Δd/t

by isolating time we have

t = Δd/v plug in given

t = 219m/(10m/s )

t = 21.9 s

It takes 21.9 s to get to the 60th floor.
