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

### Instruction:
 Camila amekwenda kupanda milima mara 7 tu katika maisha yake. Amanda amekwenda mara 8 zaidi ya Camila, na Steven amekwenda mara 15 zaidi ya Amanda. Ikiwa Camila anataka kusema kwamba amekwenda kupanda milima mara nyingi kama Steven na anapanga kwenda mara 4 kwa wiki, itamchukua muda gani Camila kufikia lengo lake?


### Response:
 Camila amekwenda kupanda milima mara 7.
Amanda amekwenda kupanda milima mara 8 * 7 = <<8*7=56>>56.
Steven amekwenda kupanda milima mara 56 + 15 = <<15+56=71>>71.
Camila anahitaji kwenda kupanda milima mara 71 - 7 = <<71-7=64>>64 ili kufikia lengo lake.
Camila anapanga kwenda kupanda milima mara 4 kwa wiki, hivyo itamchukua muda wa 64 / 4 = <<64/4=16>>16 wiki kupanda mara nyingi kama Steven.
