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

### Instruction:
 John anaweza kusoma kitabu kwa kasi ya 60% zaidi ya ndugu yake. Ikiwa ndugu yake anachukua masaa 8 kusoma kitabu, itamchukua muda gani John kusoma vitabu 3?


### Response:
 Kusoma kwa kasi ya 60% zaidi inamaanisha ndugu yake John anachukua 1+.6=1.6 mara zaidi ya John kusoma.
Hivyo John anasoma kitabu kwa masaa 8/(1.6)=<<8/(1.6)=5>>5.
Hivyo itamchukua John masaa 5*3=<<5*3=15>>15 kusoma vitabu 3.
