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

### Instruction:
 Joel ana umri wa miaka 5 na baba yake ana umri wa miaka 32. Joel atakuwa na miaka mingapi wakati baba yake atakuwa mara mbili ya umri wake?


### Response:
 Tofauti ya umri kati ya Joel na baba yake ni 32 - 5 = <<32-5=27>>27 miaka.
Ukiweka mara mbili pengo hili la miaka, utapata 27 x 2 = <<54=54>>54.
Wakati baba yake atakuwa na miaka 54, Joel atakuwa na miaka 54 / 2 = 27.
