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

### Instruction:
Gunther needs to clean his apartment.  It takes him 45 minutes to vacuum the carpets, 60 minutes to dust the furniture, 30 minutes to mop the floors in his kitchen, and 5 minutes to brush each cat, and he has three cats.  If he has 3 hours of free time available, and he uses this time to clean his apartment, how many minutes of free time will he have left after he cleans the apartment?

### 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.
