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

### Instruction:
 TJ alikimbia mbio za 10K Jumamosi iliyopita. Aliendesha nusu ya kwanza kwa dakika 20. Aliimaliza nusu ya pili kwa dakika 30. Muda wake wa wastani kwa kila kilomita ulikuwa ni upi?


### Response:
 Aliendesha kilomita 10 kwa jumla ya dakika 20 + 30 = <<20+30=50>>50.
Hivyo, aliendesha kwa kasi ya dakika 50 / 10 kilomita = <<50/10=5>>5 dakika kwa kila kilomita.
