Question

Leo reads 10 pages in 1/4 hour. What is the unit rate for pages per hour? For hours per page?

Answer 1

40 pages/hr and 1/40 hour per page

Explanation:

(a) unit rate for pages per hour:

10 pages

-------------- = 40 pages/hr

1/4 hour

(b) unit rate for hours per page:

1/4 hour

--------------- = 1/40 hour per page

10 pages

Answer 2

Leo reads 40 pages in an hour.

If you add 1/4 of an hour 4 times by itself it'll turn into 1 hour. So you need to multiply 10 pages by 4 and you'll get the amount of pages he reads per hour.
