<h3>So first of all you have Rachel who has read the book for 16 hours. Then it took Ross 790 minutes to read the book Minutes * 60 = 1 Hours so it took him/her 13.166666666667 hours So about 13 hours. Now Monica read her book in 60500 seconds in hours that is 16.805555555556 So about 16 hours as well. So I would say that finally the person who finished there book first was Ross with 13 hours. Hopefully that helps you ❤</h3>
