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

### Instruction:
 Mara moja kwa wiki, Kitty huchukua dakika 5 kukusanya vitu vya kuchezea na kupanga vyumba. Inamchukua dakika 20 nyingine kusafisha sakafu ya chumba cha kuishi, viti na mapazia. Anatumia dakika 15 kusafisha madirisha na dakika 10 kusafisha samani. Baada ya wiki 4, Kitty amekwisha kutumia muda gani kusafisha chumba cha kuishi pekee?


### Response:
 Madirisha hupigwa msasa mara moja kwa wiki kwa dakika 15 hivyo baada ya wiki 4 ni 4*15 = <<15*4=60>>60 dakika
Samanai hupigwa msasa mara moja kwa wiki kwa dakika 10 hivyo baada ya wiki 4 ni 4*10 = <<10*4=40>>40 dakika
Jumla, anatumia dakika 5+20+15+10 = <<5+20+15+10=50>>50 kusafisha chumba cha kuishi kila wiki
Baada ya wiki 4, amekwisha kutumia dakika 4*50 = <<4*50=200>>200 kusafisha chumba cha kuishi
