Answer:
To find out how many days each student will take to finish their respective books, we can use the concept of ratios.
Jayson reads the first 48 pages of a 480-page book in 3 days. To find out how many days it will take him to finish the entire book, we can set up a proportion:
48 pages / 480 pages = 3 days / x days
Cross-multiplying, we get:
48x = 480 * 3
48x = 1440
x = 1440 / 48
x = 30
So it will take Jayson 30 days to finish his book.
Marcus reads the first 50 pages of a 400-page book in 4 days. Using the same approach, we can set up a proportion:
50 pages / 400 pages = 4 days / y days
Cross-multiplying, we get:
50y = 400 * 4
50y = 1600
y = 1600 / 50
y = 32
So it will take Marcus 32 days to finish his book.
Nina reads the first 120 pages of a 600-page book in 5 days. Setting up the proportion:
120 pages / 600 pages = 5 days / z days
Cross-multiplying, we get:
120z = 600 * 5
120z = 3000
z = 3000 / 120
z = 25
So it will take Nina 25 days to finish her book.
In summary:
- Jayson will take 30 days to finish his book.
- Marcus will take 32 days to finish his book.
- Nina will take 25 days to finish her book.
