Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Kutoka saa 8:00 hadi 11:00, Mckenna anatumia saa 11:00-8:00 = 3 kazini.
Anapojiunga na watengenezaji katika chumba cha mkutano kwa ajili ya mkutano, anatumia saa nyingine 13:00-11:00 = 2 kazini.
Mpaka sasa amekaa kazini kwa saa 3+2 = 5.
Anapofanya kazi kwa saa 2 zaidi kabla ya kwenda nyumbani, jumla ya masaa ya kazi yake inakuwa 5+2 = <<5+2=7>>7.
