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

### Instruction:
How long is it before Kayla can reach the minimum age of driving of her state, which is 18, if she is currently half the age of her sister Kimiko who is 26 years old?

### Response:
 Kayla ni nusu ya umri wa Kimiko, ambayo inamaanisha yeye ana miaka 26 / 2 = <<26/2=13>>13.
Tofauti kati ya umri wa Kimiko na Kayla ni miaka 26 - 13 = <<26-13=13>>13.
Kwa kuwa umri wa kuendesha gari wa chini ni miaka 18, Kayla atalazimika kusubiri miaka 18 - 13 = <<18-13=5>>5 zaidi ili aanze kuendesha gari.
