Final answer:
To complete 1100 copies of each of the three separate two-page documents, the manager will need a total of 297 minutes.
Step-by-step explanation:
The question is asking how long it will take to complete copying three separate two-page documents, with 1100 copies of each, using a photocopier that has been established to take 45 minutes to complete 1000 copies of a one-page document. First, we need to determine how many pages in total need to be copied. Since there are three documents, each with two pages, that's a total of 3 documents × 2 pages = 6 pages to be copied for each set. Then, to find the total number of pages for 1100 sets, we multiply 6 pages × 1100 sets = 6600 pages to be copied. Given that the photocopier can copy 1000 pages in 45 minutes, we find how many 1000-page sets there are in 6600 pages by dividing 6600 pages by 1000 pages/set = 6.6 sets. To find the total time needed for these sets, we multiply 6.6 sets × 45 minutes/set. This results in 297 minutes required to complete all the copies. Therefore, the manager would need 297 minutes to complete the copying job.
