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

### Instruction:
Samantha sleeps an average of 8 hours a night. Her baby sister sleeps 2.5 times as much as Samantha does. Because her father is so tired from watching the baby, for every hour the baby sleeps, he sleeps 30 minutes. How many hours does her father sleep in a week?

### Response:
 Mtoto hulala masaa 20 kwa siku kwa sababu 2.5 x 8 = <<2.5*8=20>>20
Mtoto hulala mara 2 ya baba yake kwa sababu .5 x 4 = <<.5*4=2>>2
Baba yake hulala masaa 10 kwa usiku kwa sababu 20 / 2 = <<20/2=10>>10
Baba yake hulala masaa 70 kwa wiki kwa sababu 7 x 10 = <<7*10=70>>70
