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

### Instruction:
Micah, Dean, and Jake are all training for a marathon organized by a local NGO to support children in their town who have cancer. Micah runs 2/3 times as fast as Dean. It takes Jake 1/3 times more time to finish the marathon than it takes Mica. If Dean takes 9 hours, what's the total time the three take to complete the marathon?

### Response:
 Ikiwa Dean anachukua masaa 9 kumaliza marathon, inamchukua Micah masaa 2/3 * 9 = <<9*2/3=6>>6 kumaliza.
Inamchukua Jake masaa 1/3 zaidi kumaliza marathon kuliko Micah, jumla ya masaa 1/3 * 6 = <<6*1/3=2>>2 zaidi.
Jake anachukua jumla ya masaa 6 + 2 = <<6+2=8>>8 kumaliza marathon.
Micah, Dean, na Jake wanachukua jumla ya masaa 8 + 6 + 9 = <<8+6+9=23>>23 kumaliza marathon.
