The events are dependent.
When the first card is not replaced, you change the probability of the second card. At the very least, you have changed the total number of cards to draw from.
5 1/2 pages in 12 minutes.
11/2 pages in 12 minutes
How many pages in an hour?
well, an hour has 60 minutes
Let's write a proportion
11/2 / 12 = x/60
cross multiply
(11/2 * 60) = 12x
330 = 12x
divide both sides by 12
27.5 or 27 1/2 = x
27.5 pages per hour.
Hope this helps
