A) miss brown is reading two books every three weeks she has read 12 books so far how many weeks has she been reading so far ? b) if miss brown wants to finish reading 12 books in 15 weeks what would you tell her to change?

(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 weeks

So, the time taken to read 1 book = 3 /2  = 1/5  week

Number of books read so far = 12

Let 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  weeks

or, m= 18 weeks

Hence, 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 =

=

So, number of books Miss Brown should finish  each week  is 1.25

But 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.
