First, let's solve the equation for h:


\begin{gathered} 119+8h=271 \\ 8h=271-119 \\ 8h=152 \\ h=19 \end{gathered}

Since the book has 271 pages and she already read 119, there are 152 pages to be read.

Then, if she reads 8 pages per hour, the equation shows that she needs 19 hours, reading 8 pages per hour, to finish the remaining 152 pages.

Therefore the correct option is B.
