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

### Instruction:
Stuart is going on a cross-country trip and wants to find the fastest route. On one route the total distance is 1500 miles and the average speed is 75 MPH. On the second trip, the total distance is 750 but the average speed is 25 MPH. How long does his trip take if he goes on the fastest route?

### Response:
 Ikiwa Stuart anachagua njia ya kwanza, umbali / kasi = <<1500/75=20>>masaa 20.
Ikiwa Stuart anachagua njia ya pili, umbali / kasi = <<750/25=30>>masaa 30.
Muda jumla kwa njia ya kwanza ni masaa 20 na muda jumla kwa njia ya pili ni masaa 30.
Njia ya haraka zaidi ni njia ya kwanza kwa sababu 20 < 30.
