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

### Instruction:
 Gunther anahitaji kusafisha nyumba yake. Inamchukua dakika 45 kusafisha sakafu, dakika 60 kusafisha samani, dakika 30 kusafisha sakafu ya jikoni, na dakika 5 kusafisha kila paka, na ana paka watatu. Ikiwa ana masaa 3 ya wakati wa bure, na anatumia wakati huu kusafisha nyumba yake, atakuwa na muda wa bure wa dakika ngapi baada ya kusafisha nyumba?


### Response:
 Inachukua dakika 5 kusafisha paka mmoja, na ana paka watatu, kwa hivyo inachukua dakika 5 * 3 = <<5*3=15>>15 kusafisha paka zake.
Jumla, inachukua dakika 45 + dakika 60 + dakika 30 + dakika 15 = <<45+60+30+15=150>>150 dakika kusafisha nyumba yake.
Ikiwa ana masaa 3 ya wakati wa bure, anaweza kubadilisha hii kuwa masaa 3 * dakika 60 kwa saa = <<3*60=180>>180 dakika ya wakati wa bure.
Ikiwa anatumia dakika 150 kusafisha, atakuwa na dakika 180 - dakika 150 = <<180-150=30>>30 dakika ya wakati wa bure uliobaki.
