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

### Instruction:
 John alitumia miaka 3 ya maisha yake kuchunguza msitu. Kisha akatumia nusu ya muda huo kuandika maelezo kuhusu safari zake. Ilimchukua miezi 0.5 kuandika kitabu chake baada ya kukamilisha maelezo. Alitumia muda gani kwenye kitabu chake na kuchunguza?


### Response:
 Alitumia miaka 3 * 0.5 = <<3*.5=1.5>>1.5 kuandaa maelezo.
Ilimchukua miezi 0.5 kuandika kitabu.
Kwa hivyo ilimchukua miaka 3 + 1.5 + 0.5 = <<3+1.5+0.5=5>>5 kumaliza kila kitu.
