if Afsheen can read 39 pages of a book in half an hour how much will it take her to finish the book that is 1287 pages

We are given:

Afsheen can read 39 pages in 30 minutes

Time taken by Afsheen to read 1287 pages:

Time taken to read 1 page:

Time taken to read 1 page = time taken to read 39 pages / 39

Time taken to read 1 page = 30 minutes / 39

Time taken to read 1 page = 0.77 minutes

Time taken to read 1287 pages:

Time taken to read 1287 pages = Time taken to read 1 page * 1287

Time taken to read 1287 pages = 0.77 * 1287

Time taken to read 1287 pages = 991 minutes OR 16.52 hours (Approx)
