Math problem help—planting gardens?
Peter can replant the garden in 20 hours. Christina can replant the garden in 24 hours and Meera can replant the garden in 32 hours. They decide to work together to replant the garden. During the day, Christina leaves to do some desk work, but came back after 3 hours. Peter took a mid-day lap for 4 hours and Meera did not work the first two hours. If they started to replant the garden at 7:00 am, at what time of day did they complete the job? (To the nearest quarter of an hour)
