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

### Instruction:
 Austin na Jake wanaanza kushuka kutoka ghorofa ya 9 ya jengo wakati huo huo. Austin anatumia lifti na Jake anatumia ngazi, akishuka hatua 3 kila sekunde. Ngazi zina hatua 30 kwa kila ghorofa. Ikiwa lifti itachukua dakika moja kufika chini, baada ya muda gani Jake atafika chini?


### Response:
 Jake anahitaji kushuka hatua 30 kwenye ghorofa 9 kwa jumla ya hatua 30*9 = <<30*9=270>>270
Anashuka hatua 3 kila sekunde hivyo atashuka hatua 270 katika sekunde 270/3 = <<270/3=90>>90.
Austin atafika chini baada ya dakika moja (sekunde 60) hivyo Jake atafika chini sekunde 90-60 = <<90-60=30>>30 baadaye.
