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

### Instruction:
Before Marcus went on a road trip to LA, his car had 1728 miles on it. He filled his empty gas tank twice and used up all the gas on the trip. If Marcus's car gets 30 miles per gallon and holds 20 gallons of gas, how many miles does Marcus' car have on it now?

### Response:
 Kwanza, tafuta jumla ya mafuta kwenye tangi ya Marcus: 20 galoni * 30 maili/galoni = <<20*30=600>>600 maili
Kisha, zidisha idadi hiyo na idadi ya kujaza ili kupata jumla ya maili za safari: 600 maili/kujaza * 2 kujaza = 1200 maili
Hatimaye, ongeza idadi hiyo na idadi ya maili ya awali kwenye gari la Marcus ili kupata idadi ya mwisho ya maili: 1728 maili + 1200 maili = <<1728+1200=2928>>2928 maili
