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

### Instruction:
Harvey and his friend Sam decided to run a footrace in their school track field to see who was better at running. While at it, Harvey runs 8 miles more than his friend Sam, who runs a total of 12 miles. Calculate the total number of miles the two friends run together.

### Response:
 Ikiwa Harvey alikimbia maili 8 zaidi, basi alikimbia jumla ya maili 12 + 8 maili = 20 maili.
Marafiki hao wawili walikimbia jumla ya maili 20 + 12 maili = <<20+12=32>>32 maili.
