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

### Instruction:
 Patrick ni nusu ya umri wa kaka yake mkubwa Robert. Ikiwa Robert atatimiza miaka 30 baada ya miaka 2, Patrick ana umri gani sasa?


### Response:
 Robert atakuwa na umri wa miaka 30 baada ya miaka 2, hivyo sasa ana umri wa 30 - 2 = <<30-2=28>>28 miaka.
Hivyo, Patrick ana umri wa 1/2 * 28 = <<1/2*28=14>>14 miaka.
