C. 17 Hours

D. 15.5 Hours

**B. 16.5 Hours**

Arif can Read 39 pages in 30 minutes.

How much time is required to read 1287 pages?

39 page read time = 30 minute

01 page read time=30/39=0.76923 minute

1287 pages read time=0.769*1287=990 minute

990 conversion into hours = 990/60 = 16.5 Hours

Another Simple Explanation:

39 pages for a half hour equals 78 pages per hour and if the book has 1287 pages then 1287 pages divided by 78 pages per hour gives you 16.5.
