Answer:
It will take him 20 days to read a 300-page book.
Explanation:
Given:
Stephen read a 90-page book in 6 days.
If he continues reading at that rate.
Now, to find the time it will take him to read a 300-page book.
So, we solve using unitary method:
If, Stephen read 90 pages in 6 days.
So, Stephen read 1 page in =
days.
Thus, Stephen read 300 page in =
![(6)/(90) * 300](https://img.qammunity.org/2021/formulas/mathematics/middle-school/riudf0g5gc6jtiezg8wmlnjqsldb89dw98.png)
![=(1800)/(90)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ru3od98n5n2n4shfbj274w3a5zny8y62hu.png)
![=20\ days.](https://img.qammunity.org/2021/formulas/mathematics/middle-school/zqg24ggf0hncjhrrrbabf3x7qa8tbwqcc1.png)
Therefore, it will take him 20 days to read a 300-page book.
