If 5 identical machines take 5 minutes to manufacture 5 identical items, how many minutes will it take 100 of these machines to manufacture 100 items?

If 5 machines make 5 items in 5 minutes, each individual machine takes 5 minutes to make 1 item. Thus, 100 machines working simultaneously will each complete 1 item in 5 minutes, resulting in 100 total items in 5 minutes.
