Answer:
The unit rate of pages per hour is 36 pages per hour .
Step-by-step explanation:
Given as :
Penny reads 12 pages in one-third of an hour.
∵ 1 hour = 60 minutes
So , one-third of an hour = [tex]\dfrac{1}{3}[/tex] × 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 = [tex]\dfrac{12}{20}[/tex]
∴ In 60 min , the number of pages read by Penny = [tex]\dfrac{12}{20}[/tex] × 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
