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

### Instruction:
John spent 3 years of his life exploring the jungle.  He then spent half as much time writing up notes about his travels.  It took .5 years to write his book once he was done with the notes.  How long did he spend on his book and exploring?

### 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.
