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

### Instruction:
Janet has to drive 30 miles east from home to see her dermatologist and 50 miles west from home to see her gynecologist. If she has appointments with both doctors on the same day, how many gallons of gas does she use driving to both appointments and back home again, if her car gets 20 miles per gallon?

### Response:
 Kwanza tafuta idadi jumla ya maili anaouendesha kwenda kwa daktari wa ngozi na kurudi nyumbani kwake: maili 30 * 2 = <<30*2=60>>60 maili
Kisha tafuta idadi jumla ya maili anaouendesha kwenda kwa daktari wa uzazi na kurudi nyumbani kwake: maili 50 * 2 = <<50*2=100>>100 maili
Kisha ongeza maili za safari hizo mbili ili kupata idadi jumla ya maili anaouendesha: maili 60 + maili 100 = <<60+100=160>>160 maili
Kisha ugawanye idadi ya maili anaouendesha na uwezo wa gari lake wa kutumia mafuta ili kupata galoni ngapi za mafuta anahitaji: maili 160 / maili 20/galoni = <<160/20=8>>8 galoni
