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

### Instruction:
 Casey anatumia masaa 6 kukamilisha mbio za marathon, wakati Zendaya anatumia muda mara 1/3 zaidi kufunika umbali huo huo. Muda wastani wanaotumia wote kukamilisha mbio ni upi?


### Response:
 Zendaya anatumia 1/3 * masaa 6 = <<1/3*6=2>>masaa 2 zaidi kukamilisha marathon.
Kukamilisha marathon, Zendaya anatumia masaa 6 + masaa 2 = <<6+2=8>>masaa 8.
Jumla ya muda wanaotumia wote kukamilisha marathon ni masaa 8 + masaa 6 = <<8+6=14>>masaa 14.
Muda wastani ambao Casey na Zendaya wanatumia kukamilisha marathon ni masaa 14 / watu 2 = <<14/2=7>>masaa 7/kila mtu.
