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

### Instruction:
John trains for ultramarathons.  He starts only able to run 8 hours straight but eventually increases that by 75%.  He also increases his speed of 8 mph by 4 mph.  How far can he run now?

### Response:
 Anazidisha muda anaweza kukimbia kwa saa 8 * 75% = <<8*75*.01=6>>6 saa
Hivyo sasa anaweza kukimbia kwa saa 8 + 6 = <<8+6=14>>14
Kasi yake sasa ni maili 8 + 4 = <<8+4=12>>12 kwa saa
Hivyo anaweza kukimbia kwa umbali wa 14 * 12 = <<14*12=168>>168 maili
