Question

Lin is reading a 47 page book. She read the first 20 pages in 35 minutes. If she continues to read at the same rate will she be able to complete in under an hour? If not, how much more time is needed?

Answer 1

No, 40 pages would take 70 minutes.

Explanation:

20 more pages would take 35 more minutes which would be 40 pages at 70 minutes, then you will divide your 7 pages left by the 35 minutes it took to read the the first two 20 page sections of the book.

35 min.+ 35 min = 70 min. 35 mins./7 pages = 5 minutes

So it took a total of 75 minutes for Line to read her 47 page book.
