Question

Jack reads 40 pages per hour. Dave reads at the rate of 3 5 of a pages per minute. Who reads faster? By how many pages per hour faster?

Answer 1

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.
