The answer to this question is:
<span><span>A. The length is 8 inches, and the width is 5 inches.
</span>The scale factor can be found in the question, <em>"</em></span><span><em>the art team made a scale drawing of the top of the box using a scale of 3 inches to 1 inch"</em>. This means the scale drawing should be divided by a scale factor of 3:1 (simplified into 3).
</span>
The scale factor is then divided with the components provided (24 inches in length, 15 inches in width).
(24/3) = 8 inches
(15/3) = 5 inches
Your answer is length = 8 inches, width = 5 inches.
This means that...
the first worker does 1/8 of the job each hour.
the second worker does 1/4 of the job each hour.
the third worker does 1/4 of the job each hour.
So together they get 1/8+1/4+1/4 of the job done per hour.
Rate: 5/8 of the job per hour
Now if we know the rate, the job will be finished in...
1/(5/8) hours ----> 1.6 hours or 1 hour and 36 minutes
answer: 1.6 hours or 1 hour and 36 minutes
