Final answer:
To find out how many days it will take Sory to finish the book, set up the equation x * d = 600 and solve for d. Then, divide 600 by x to get the number of days.
Step-by-step explanation:
Let's assume Sory reads x pages each day and the book is 600 pages long. To find out how many days it will take him to finish the book, we can set up the equation:
x * d = 600
Where d is the number of days. Now let's solve for d:
d = 600 / x
So, it will take Sory 600 / x days to finish the book.
