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

### Instruction:
Mary and Jimmy start running from the same spot, but in opposite directions. Mary runs at 5 miles per hour and Jimmy runs at 4 miles per hour. What is the distance between them after 1 hour?

### Response:
 Baada ya saa moja, Mary atakuwa amesafiri maili 5 kwa saa * 1 saa = <<5*1=5>>5 maili.
Baada ya saa moja, Jimmy atakuwa amesafiri maili 4 kwa saa * 1 saa = <<4*1=4>>4 maili.
Kwa kuwa wanakimbia kwa mwelekeo tofauti, umbali kati yao utakuwa maili 5 + maili 4 = <<5+4=9>>9.
