amanda read 15 pages of her 150-page book in 2 hours. at this rate, how long will it take her to read the entire book? 2 hours 5 hours 10 hours 20 hours
Step One: 150 Pages ÷ 15 Pages = 10
Step Two: 10 × 2 = 20 Hours
Answer: Amanda read the book in 20 hours.
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 =\(\dfrac{2}{15}\) hour
Now, the number of hours taken by Amanda to read 150 pages =\(\dfrac{2}{15}\times150=20\) hours.
Hence, she takes 20 hours to read the entire book .
