Question

Penny reads 12 pages in one-third of an hour. What is the unit rate for pages per​ hour? For hours per​ page?

Answer 1

The unit rate of pages per hour is 36 pages per hour .

Explanation:

Given as :

Penny reads 12 pages in one-third of an hour.

∵ 1 hour = 60 minutes

So , one-third of an hour =
`(1)/(3)` × 60 min

Or, one-third of an hour = 20 min

Now, According to question

∵ In 20 min , the number of pages read by Penny = 12

So, In 1 min , the number of pages read by Penny =
`(12)/(20)`

∴ In 60 min , the number of pages read by Penny =
`(12)/(20)` × 60 min

i.e In 1 hour ,the number of pages read by Penny = 12 × 3 = 36 pages

Hence,The unit rate of pages per hour is 36 pages per hour . Answer
