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

### Instruction:
Camila has only gone hiking 7 times in her life. Amanda has gone on 8 times as many hikes as Camila, and Steven has gone on 15 more hikes than Amanda. If Camila wants to say that she has hiked as many times as Steven and plans to go on 4 hikes a week, how many weeks would it take Camila to achieve her goal?

### 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.
