The area of the room must equal the sum of the areas of the tiles...
20*30=n(2*3)
600=6n
n=100
So 100 tiles are needed.

What's the question
Step-by-step explanation:
You didn't give an actual question, just background information.
We are given the distance covered by an elevator = 310 feet.
Time taken to cover 310 feet = 10 seconds.
<em>Rate of the elevator at it run = 310/10 = 31 feet per seconds.</em>
We need to find how many feet an elevator can travel in 12 seconds.
In order to find the distance covered by an elevator in 12 seconds, we need to multiply 12 by the rate of the elevator.
<h3>Therefore, distance covered by the elevator in 12 seconds = 12 × 31 </h3><h3> = 372 feet.</h3>
