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

### Instruction:
Samuel is driving to San Francisco’s Comic-Con in his car and he needs to travel 600 miles to the hotel where he made a reservation. At first, he drives at 50 miles/hour for 3 hours straight, then he speeds up to 80 miles/hour for 4 hours. How far is he from the hotel?

### Response:
 Kwanza, akiwa na kasi ya maili 50 kwa saa, anasafiri maili 50 kwa saa * masaa 3 = <<50*3=150>>150.
Baada ya hapo, anaongeza kasi, akisafiri maili 80 kwa saa * masaa 4 = <<80*4=320>>320.
Mpaka sasa amesafiri maili 320 + 150 = <<320+150=470>>470.
Yuko umbali wa maili 600 - 470 = <<600-470=130>>130 kutoka hotelini.
