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

### Instruction:
Austin and Jake start descending from the 9th floor of a building at the same time. Austin uses the elevator and Jake uses the stairs, descending 3 steps every second. The stairs have 30 steps across each floor. If the elevator will take a minute to get to ground level, how many seconds later will Jake get to the ground floor?

### 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.
