A COPY MACHINE CAN DUPLICATE 18 PAGES IN 45 SECONDS. AT THIS RATE,HOW MANY PAGES CAN BE DUPLICATED IN 60 SECONDS?
24 pages
A simple ratio can be used
18 45
--- = ---
X 60
18 x 60
------- = 24 pages
45
You can set up a proportion and cross multiply.
18/45 = x/60
45x = 1080
x = 24

To find out how many pages can be duplicated in 60 seconds, we can use the concept of proportion. Since we know that a copy machine can duplicate 18 pages in 45 seconds, we can set up the following proportion:
18 pages / 45 seconds = x pages / 60 seconds
To solve for x, we can cross-multiply and then divide:
18 * 60 = 45 * x
1080 = 45x
Now, we can divide both sides of the equation by 45 to solve for x:
1080 / 45 = x
24 = x
Therefore, at this rate, the copy machine can duplicate 24 pages in 60 seconds.
