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

### Instruction:
 Carlos na Diego wanakimbia karibu na kona. Carlos anakimbia karibu na kona nzima kwa dakika 3. Diego anakimbia nusu ya kona kwa dakika 2.5 na kisha anatumbukizwa na mbwa na hawezi kumaliza. Kukisia kwamba alishikilia kasi ile ile kwa mbio nzima, wastani wa muda ungekuwa sekunde ngapi kwa washindani?


### Response:
 Kama angekamilisha mbio, ingekuwa mbio za dakika 5 kwa sababu 2.5 x 2 = <<2.5*2=5>>5
Wastani wa muda ungekuwa dakika 4 kwa sababu (3 + 5)/2 = <<(3+5)/2=4>>4
Wastani ungekuwa sekunde 240 kwa sababu 4 x 60 = <<4*60=240>>240
