First, we need to get the total area of the rectangular pool.
Area = l * w
Area = 20 ft * 50 ft
Area = 1000 ft^2
Then the deck is 456 ft^2 with the width of 20ft, the same as the rectangular pool.
Area = l * w
456 = l * 20
l = 456 / 20
l = 22.8 ft.
So the walkway is 22.8ft wide.
It will take Fred 42 minutes to type and spell check 60 pages.
- Let the first scenario be A.
- Let the second scenario be B.
- Let the unknown time be X.
Given the following data;
- Number of pages A = 13 pages
- Number of pages B = 60 pages
To find how long it takes him to type and spell check 60 pages;
We would use direct proportion to express the work described and solve for the unknown variable (time).

Cross-multiplying, we have;
×
× 

<em>X = 41.54 ≈ 42 minutes</em>
Therefore, it will take Fred 42 minutes to type and spell check 60 pages.
