Answer:
99 minutes
Explanation:
Since the time it takes Winnie to word process and spell check is proportional to the number of pages, we can determine how long it takes her to word process and spell check 45 pages using a proportion:
22 min / 10 pages = x min / 45 pages
22/10 = x/45
(11/5 = x/45) * 45
495/5 = x
99 = x
Thus, it takes Winnie 99 minutes to word process and spell check 45 pages.
