Answer:
Step-by-step explanation:
To find the number of pages of the book in the given hour:
To find the number of pages in 2 1/5 hours, multiply the number of pages read in 1 hour by 2 1/5 hours.
![\sf \text{ Number of pages read in 2 $\dfrac{1}{5}$ hours = $\dfrac{1}{3}*2\dfrac{1}{5}$ }](https://tex.z-dn.net/?f=%5Csf%20%5Ctext%7B%20%20Number%20of%20pages%20read%20in%202%20%24%5Cdfrac%7B1%7D%7B5%7D%24%20hours%20%3D%20%24%5Cdfrac%7B1%7D%7B3%7D%2A2%5Cdfrac%7B1%7D%7B5%7D%24%20%7D)
![\sf = \dfrac{1}{3}*\dfrac{11}{5}\\\\=\dfrac{11}{15}](https://tex.z-dn.net/?f=%5Csf%20%3D%20%5Cdfrac%7B1%7D%7B3%7D%2A%5Cdfrac%7B11%7D%7B5%7D%5C%5C%5C%5C%3D%5Cdfrac%7B11%7D%7B15%7D)
![\sf \text{Number of pages read more in 2 $\dfrac{1}{5}$ hours = $\dfrac{11}{15}-\dfrac{1}{3}$}](https://tex.z-dn.net/?f=%5Csf%20%5Ctext%7BNumber%20of%20pages%20read%20more%20in%202%20%24%5Cdfrac%7B1%7D%7B5%7D%24%20hours%20%3D%20%24%5Cdfrac%7B11%7D%7B15%7D-%5Cdfrac%7B1%7D%7B3%7D%24%7D)
![\sf =\dfrac{11}{15}-\dfrac{1*5}{3*5}\\\\=\dfrac{11}{15}-\dfrac{5}{15}\\\\=\dfrac{6}{15}](https://tex.z-dn.net/?f=%5Csf%20%3D%5Cdfrac%7B11%7D%7B15%7D-%5Cdfrac%7B1%2A5%7D%7B3%2A5%7D%5C%5C%5C%5C%3D%5Cdfrac%7B11%7D%7B15%7D-%5Cdfrac%7B5%7D%7B15%7D%5C%5C%5C%5C%3D%5Cdfrac%7B6%7D%7B15%7D)
Answer:
Step-by-step explanation:
