Question

Sumaya is reading a book with 288 pages. She has already read 90 pages. She plans to read 20 more pages each day until she finishes the book. Determine how many days Sumiya will need to finish the book. In your answer, count part of a day as a full day. Show that your answer is reasonable

Answer 1

Answer: 10 days

Working:
(288 - 90) / 20 = 9.9
9.9 rounded up to the nearest whole number will be 10
Therefore, she will take 10 days

Sorry I can only show the working, I don't know how to put the working into words to explain how the answer is reasonable.
