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

### Instruction:
A building has 10 floors. It takes 15 seconds to go up the stairs to the even-numbered floors and 9 seconds to go up to the odd-numbered floors.  This includes getting to the first floor. How many minutes does it take to get to the 10th floor?

### Response:
 Kupanda ngazi kwenda ghorofa zenye namba za juu (2, 4, 6, 8, 10) inachukua sekunde 5 x 15 = 75.
Kupanda ngazi kwenda ghorofa zenye namba za ganzi (1, 3, 5, 7, 9) inachukua sekunde 5 x 9 = 45.
Hivyo jumla inachukua sekunde 75 + 45 = 120 kupanda hadi ghorofa ya 10.
120 sekunde ni 120/60 = 2 dakika.
