They start at 12:0012:00 pm, and Chandler has a dentist appointment from 12:1012:10 pm to 12:3012:30, after which he comes back and continues solving LMT problems. The time it will take for them to finish solving 5050 LMT problems, in hours, is m/nm/n ,where mm and nn are relatively prime positive integers. Find m+nm +n.
