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

### Instruction:
Arnold owns three cars. The first car averages 50 miles per gallon of gas. The second car averages 10 miles per gallon of gas. And the third car averages 15 miles per gallon of gas. He splits his 450-mile monthly driving mileage equally amongst his three cars.  If gas costs $2 per gallon, how much does he spend on gas each month?

### Response:
 Anasafiri kila gari maili 150 kwa sababu 450 / 3 = <<450/3=150>>150
Gari la kwanza litahitaji galoni 3 za mafuta kwa sababu 150 / 50 = <<150/50=3>>3
Gari la pili litahitaji galoni 15 za mafuta kwa sababu 150 / 10 = <<150/10=15>>15
Gari la tatu litahitaji galoni 10 za mafuta kwa sababu 150 / 15 = <<150/15=10>>10
Jumla atahitaji galoni 28 kwa sababu 3 + 15 + 10 = <<3+15+10=28>>28
Hii itamgharimu $56 kwa sababu 28 x $2 = $<<28*2=56>>56
