We have been given that
Luke can read 4 3/4 pages in 15 minutes.
Hence in 1 minute Luke can read 19/60 pages.
Sarah can read 1 1/2 pages in 4 minutes.
Hence, in 1 minute Sarah can read 3/8 pages.
Now, let us find how many pages they can read in 2 hours = 120 minutes.
In 2 hours Luke can read pages.
In 2 hours Sarah can read pages.
The difference in the number of pages is 45 - 38 = 7 pages.
Therefore, Sarah can read 7 more pages than Luke in 2 hours.
