20 printers 20 books 20 minutes
If you had 120 printers (6 times as many) and you still wanted to print 20 books, it would take you 1/6 of the time = 20/6 = 3 minutes 40 seconds
Now if you wanted to increase the volume of books required to 120, (6 fold) and you still had those 120 printers, it would take you 6 times as long ie 3 minutes 40 seconds x 6 = 20 minutes
If you had 120 printers and wanted to print 120 books it would take you 20 minutes.
