 
 <translate> Gwendolyn just brought a book from the library, having 20 paragraphs per page, and since the book has 50 pages, the number of paragraphs in the book is 50 * 20 = 1000 paragraphs. If each paragraph has 10 sentences, the book's number of sentences is 1000 * 10 = 10000 sentences. Since Gwendolyn can read 200 sentences of a book in 1 hour, she will read 10000 sentences in 10000 / 200 = 50 hours. So the answer is 50. <ibo> Gwendolyn ka wetara akwụkwọ site n'ọ́bá akwụkwọ, nke nwere paragraf 20 n'otu peeji, ebe ọ bụkwa na akwụkwọ ahụ nwere peeji 50, ọnụ ọgụgụ paragraf dị n'akwụkwọ ahụ bụ 50 * 20 = paragraf 1000.
