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

### Instruction:
Carl is figuring out how much he'll need to spend on gas for his upcoming road trip to the Grand Canyon. His car gets 30 miles per gallon in cities and 40 miles per gallon on the highway. The distance from his house to the Grand Canyon, one way, is 60 city miles and 200 highway miles.  If gas costs $3.00 per gallon, how much will Carl need to spend?

### Response:
 Kwanza, tafuta idadi ya maili za miji ambazo Carl atatembea kwenda na kurudi kwa kuzidisha idadi ya maili za miji kwa njia moja: 60 maili * 2 = <<60*2=120>>120 maili
Kisha tafuta idadi ya maili za barabara kuu ambazo Carl atatembea kwenda na kurudi kwa kuzidisha idadi ya maili za barabara kuu kwa njia moja: 200 maili * 2 = <<200*2=400>>400 maili
Sasa gawanya idadi ya maili za miji za kwenda na kurudi na idadi ya maili za miji kwa galoni ambazo gari la Carl linapata: 120 maili / 30 mpg = <<120/30=4>>4 galoni
Sasa gawanya idadi ya maili za barabara kuu za kwenda na kurudi na idadi ya maili za barabara kuu kwa galoni ambazo gari la Carl linapata: 400 maili / 40 mpg = <<400/40=10>>10 galoni
Sasa ongeza galoni za maili za barabara kuu na maili za miji ili kupata jumla ya galoni ambazo Carl anahitaji kununua: 10 galoni + 4 galoni = <<10+4=14>>14 galoni
Hatimaye, zidisha idadi ya galoni ambazo Carl anahitaji kununua na gharama ya kila galoni ili kujua kiasi anachotumia: 14 galoni * $3.00 = $<<14*3=42.00>>42.00
