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

### Instruction:
Tony can run a mile twice as fast as Tina, who with a time of 6 minutes is one-third as fast a runner as Tom.  What are all three of their mile times when added together?

### Response:
 Tony atakuwa mara mbili kwa kasi kama Tina, ambaye anakimbia kwa dakika 6 hivyo atakimbia maili kwa dakika 6/2 = <<6/2=3>>3.
Tom ni mara tatu kwa kasi kama Tina, ambaye alikimbia maili kwa dakika 6 hivyo atakimbia maili kwa dakika 6/3 = <<6/3=2>>2.
Ukiwa unaweka pamoja muda wao wote, Tony atakimbia maili kwa dakika 3, Tom atakimbia kwa dakika 2, na Tina atakimbia kwa dakika 6 kwa jumla ya dakika 3+2+6 = <<3+2+6=11>>11.
