Given:

Number of pages read by Jack = 40 per hour

Rate of reading by Dave =3/5 of a page in a minute

To find:

The person who reads faster and by how many minutes.

Solution:

If Dave reads 3/5 of a page in a minute then in an hour he would read,


\Rightarrow(3)/(5)*60 \text{ pages } (60 minutes = 1 hour)


\Rightarrow36 pages in an hour

The difference between pages read by Jack and Dave is
40-36=4

Therefore, Jack reads faster than Dave by 4 pages.
