Kenya starts her chores at 10:00 a.m. She took 20 minutes to clean the yard, 1 hour and 15 minutes to clean the house and 15 minutes to tidy the garage. At what time did she finish her chores.
She started at 10:00 so you add 20 minutes for the yard(10:20). Then you add one hour and 15 minutes for the house(11:35). Then add the last 15 minutes for the garage(11:50). 11:50am is your answer.
