Accepted Solution
A:
Answer: (A) Miss Brown has been reading for 18 weeks so far.(B) So as to complete the given target, she needs to SLOW her reading rate by 0.25 books per week.Step-by-step explanation:The number of weeks it takes to read 2 books by Miss Brown = 3 weeksSo, the time taken to read 1 book = 3 /2 = 1/5 weekNumber of books read so far = 12Let us assume it takes m weeks to read 12 books.Now, Time taken to read 12 books = 12 x ( Time taken to read 1 book)⇒ m= 12 x ( 1.5 week) = 18 weeksor, m= 18 weeksHence, Miss Brown has been reading for 18 weeks so far.Also, Miss Brown wants to finish 12 books in 15 weeks.So, the number of books finished each week = [tex]= \frac{\textrm{Total number of weeks she has}}{\textrm{Total books she want to finish}}[/tex]=[tex]\frac{15}{12} = 1.25[/tex]So, number of books Miss Brown should finish each week is 1.25But here current reading rate is 1.5 books per week .So as to complete the given target, she needs to SLOW her reading rate by 0.25 books per week.
