Answer: 20 hours

Step-by-step explanation:

Given: The number of hours taken by Amanda to read 15 pages = 2 hours

Using unitary method, the number of hours taken by Amanda to read 1 page =[tex]\dfrac{2}{15}[/tex] hour

Now, the number of hours taken by Amanda to read 150 pages =[tex]\dfrac{2}{15}\times150=20[/tex] hours.

Hence, she takes 20 hours to read the entire book .
