Answer 2

30 days

Step-by-step explanation:

if she reads the book for 21 days and 5 hrs each day she will take 105 hrs to complete 3 book

so for 1 book she takes 105/3= 35 hrs

for 6 book she would take 6*35 =210hr

according to question she will read 7 hours per day so 210/7 = 30

so the answer is 30 days
