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

### Instruction:
Xena is trying to outrun a dragon to get to the safety of a cave it's too big to fit into. Xena has a 600 foot head start, but the dragon can burn her if it gets within 120 feet of her. If Xena runs 15 feet per second and the dragon flies 30 feet per second, how many seconds does Xena have to get to the cave?

### Response:
 Kwanza tafuta kasi ya joka ni kiasi gani kubwa kuliko ya Xena: futi 30/sekunde - futi 15/sekunde = <<30-15=15>>15 futi/sekunde.
Kisha tafuta ukubwa wa pengo ambalo joka linahitaji kulifunga ili kumchoma Xena: futi 600 - futi 120 = <<600-120=480>>480 futi.
Kisha gawanya umbali na tofauti ya kasi ili kupata sekunde ngapi inachukua kwa joka kufika karibu ya kumchoma Xena: futi 480 / futi 15/sekunde = <<480/15=32>>32 sekunde.
