If joanne can read 18 pages in 30 mins how long will it take her to read 63 pages? Explain how yu got your answer

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.
