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

### Instruction:
 Jimmy anataka kucheza katika bwawa la kuogelea lenye hewa katika nyuma ya nyumba yake. Bwawa la kuogelea ni tupu na gari limefungwa, hivyo hawezi kutumia hose kujaza bwawa. Anapata ndoo ya lita 2 na kuhesabu kuwa inachukua sekunde 20 kujaza ndoo kutoka kwenye bomba na kuipeleka kwenye bwawa ambapo anamwaga maji. Ikiwa bwawa linahifadhi lita 84 za maji, Jimmy atatumia muda gani kujaza bwawa?


### Response:
 Kujaza bwawa, Jimmy anahitaji safari 84 / 2 = <<84/2=42>>42.
Ikiwa kila safari inamchukua Jimmy sekunde 20, atatumia sekunde 20 * 42 = <<20*42=840>>840 kujaza bwawa.
Hii inamaanisha Jimmy atatumia 840 / 60 = <<840/60=14>>14 dakika kujaza bwawa.
