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

### Instruction:
Drew is 5 years older than Maya. Peter is 4 years older than Drew. John is 30 and is twice as old as Maya. In 2 years, Jacob will be exactly half of Peter’s age. How old is Jacob now?

### Response:
 Maya ana miaka 30 / 2 = <<30/2=15>>15.
Drew ana miaka 15 + 5 = <<15+5=20>>20.
Peter ana miaka 20 + 4 = <<20+4=24>>24.
John ana miaka 30 na Drew ana miaka 20, hivyo John ana miaka 30 + 12 = <<30+12=42>>42.
Baada ya miaka 2, Peter atakuwa na miaka 24 + 2 = <<24+2=26>>26.
Nusu ya umri wa Peter baada ya miaka 2 ni 26 / 2 = <<26/2=13>>13, ambayo ndiyo umri wa Jacob baada ya miaka 2.
Jacob sasa ana miaka 13 - 2 = <<13-2=11>>11.
