Answer:
If it took Lauren 14 hours to read a 420-page book, we can calculate her reading rate as 420 pages / 14 hours = 30 pages per hour.
Explanation:
To find out how long it will take her to read a 600-page book, we divide the total number of pages (600) by her reading rate (30 pages per hour): 600 pages / 30 pages per hour = 20 hours.
Therefore, it will take Lauren approximately 20 hours to read a 600-page book at the same rate.
Hope this helps!
