Answer :
To find out how many hours it will take Moira to read the entire book, we need to determine how many sets of 10 pages (which she reads in one hour) she can complete in reading the entire book.
Here's how you can solve this problem step-by-step:
1. Understand the Problem:
- Moira reads 10 pages in 1 hour.
- The book is 210 pages long.
2. Determine the Total Time Required:
- Since Moira reads 10 pages per hour, you want to find out how many times she needs to read those 10 pages to finish the 210 pages of the book.
3. Divide the Total Pages by Pages Per Hour:
- You can find out how many hours it will take by dividing the total pages of the book by the number of pages she reads in one hour:
- [tex]\( \frac{210 \text{ pages}}{10 \text{ pages/hour}} = 21 \text{ hours} \)[/tex]
Therefore, it will take Moira 21 hours to read the entire book.
The correct option to solve this problem is B. Divide 210 by 10.
