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

### Instruction:
Alex has not washed his clothes for a month; 18 shirts, 12 pants, 17 sweaters, and 13 jeans are waiting to be washed. Alex's washing machine can wash a maximum of 15 items per cycle. Each cycle takes 45 minutes. How many hours will it take the washing machine to wash all the clothes?

### Response:
 Jumla ya mashati na suruali ni 18 + 12 = <<18+12=30>>30
Ukiongeza sweta na jeans, jumla ya nguo inakuwa 30 + 17 + 13 = <<30+17+13=60>>60
Kufua nguo, Alex atahitaji mzunguko wa 60 nguo / 15 nguo/mzunguko = <<60/15=4>>4 mizunguko
Kwa dakika 45 kwa kila mzunguko, mashine ya kufua itachukua dakika 45/mzunguko * 4 mizunguko = <<45*4=180>>180 dakika
Kwani saa ina dakika 60, mashine ya kufua itachukua dakika 180 / 60 dakika/saa = <<180/60=3>>3 masaa
