Answer:
C
Step-by-step explanation:
after 12 min she read
[tex]5 \frac{1}{2} [/tex]
pages
also mean she read 11 pages ( 2 * 5 + 1 ) after 12 min
The amount of page she read per min :
- 11 / 12 = 11/12 ( 11 / 12 cuz it is page / min)
The amount of page she read per hour :
- 11/12 * 60 = 55 page/hour
C is
[tex]27 \frac{1}{2} [/tex]
also mean 55 pages / hour (27 * 2 + 1)
so the answer is C
Done :))
