Every 18 pages takes 30 minutes to read. Since she has to read 63 pages  more pages, it would take more than 90 minutes(18+18+18 =54 pages) but less than 120 minutes (18+18+18+18=72) pages. 9 more pages need to be read and that would be dome in half the time of 18 pages or 15 minutes. 90 minutes plus 15 minutes= 105 minutes or 1 hour 45 minutes.
