Step-by-step reasoning process: From 8:00 to 11:00, Mckenna spends 11:00 - 8:00 = 3 hours at work. When she joins the developers in the conference room for the meeting, she spends an additional 13:00 - 11:00 = 2 hours at work. So far, she has spent 3 + 2 = 5 hours at work. When she works for an additional 2 hours before heading home, her total work hours become 5 + 2 = 7 hours.
The question and answer:
Question and answer:
Mckenna starts her day at 8:00 a.m. She works in her office up to 11:00 a.m. then joins her team of developers at the conference room to talk about projects up to 13:00, from which she works for another two hours and then heads home. How many hours does Mckenna stay at work?
