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

### Instruction:
Two alien spacecraft on a sightseeing tour of Earth left New Orleans airport at 3:00 pm to travel the 448-mile distance to Dallas by air.  Traveling nonstop, the first spacecraft landed in Dallas at 3:30 pm, while the second spacecraft landed in Dallas thirty minutes later. Assuming both spacecraft traveled at constant speed, what was the difference in speed, in miles per hour, between the two spacecraft?

### Response:
 Ndege ya kwanza iliruka kwa dakika 30, au 30/60=<<30/60=0.5>>0.5 saa.
Ndege ya pili iliruka kwa dakika 30+30=<<30+30=60>>60, au 1 saa.
Hivyo ndege ya kwanza ilisafiri kwa kasi ya maili 448 katika 0.5 saa, au 448/(0.5)=896 maili kwa saa.
Ndege ya pili ilisafiri maili 448 katika 1 saa, au 448/1=<<448/1=448>>448 maili kwa saa.
Tofauti ya kasi, kwa maili kwa saa, kati ya ndege hizo mbili ilikuwa 896-448=<<896-448=448>>448 maili kwa saa.
