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,
[tex]\Rightarrow\frac{3}{5}\times60 \text{ pages }[/tex] (60 minutes = 1 hour)
[tex]\Rightarrow36[/tex] pages in an hour
The difference between pages read by Jack and Dave is [tex]40-36=4[/tex]
Therefore, Jack reads faster than Dave by 4 pages.
