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

### Instruction:
 Kuna vumbi nyingi katika nyumba ya Susie. Inamchukua masaa 2 kusafisha nyumba nzima. Anaweza kusafisha kila chumba kwa dakika 20. Ana vyumba vingapi katika nyumba yake?


### Response:
 Susie anatumia 2*60 = <<2*60=120>>120 dakika kusafisha.
Ikiwa inamchukua dakika 20 kusafisha kila chumba, basi ana vyumba 120/20 = <<120/20=6>>6 katika nyumba yake.
