Explanation: The time starts at 12 p.m. Monday from 2:00 p.m. to 2:00 p.m. Monday after that = 7 days 2 hours = 170 hours.In 170 hours, the watch gains (2 + 4 4/5 minutes) or 34/5 minutes.In 170 hours, 34/5 minutes are acquired.In (170 x 5/34 x 2 hrs)= 50 hrs, 2 minutes are gained.The watch is accurate for two days and two hours. after the hour of 12 p.m. It will be correct at 2 p.m. on Wednesday.
