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

### Instruction:
Sandy's goal is to drink 3 liters of water in a day. She drinks 500 milliliters of water every after 2 hours. After how many hours will she be able to drink a total of 3 liters of water?

### Response:
 Kwa kuwa kuna mililita 1000 katika lita 1, basi lita 3 ni sawa na 3 x 1000 = <<3*1000=3000>>3000 mililita.
Sandy ataweza kunywa lita 3 za maji katika 3000/500 = <<3000/500=6>>6 seti za mililita 500 ya maji.
Hivyo, ataweza kunywa jumla ya lita 3 baada ya seti 6 x kila baada ya masaa 2 = 12 masaa.
