Mya works on Saturdays and then attends a study group. She needs to be home before her younger brother. She walks from work to the study group in 5 minutes. She studies for 40 minutes. She takes 5 minutes to walk to the bus stop. The bus ride is 30 minutes long. It takes her 10 minutes to walk home from where the bus drops her off. If Mya is to be home by 5p.m., what time should she leave work?
