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

### Instruction:
Once a week, it takes Kitty 5 minutes to pick up toys and straighten the living room.  It takes another 20 minutes to vacuum the living room floor, seating and drapes.  She spends 15 minutes cleaning the windows and 10 minutes dusting the furniture.  After 4 weeks, how long has Kitty spent cleaning just the living room?

### 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
