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

### Instruction:
Biff is getting ready for a long bus trip. He spends $11 on the ticket, $3 on drinks and snacks, and $16 on a new pair of headphones to listen to music. Biff plans to do online tasks using the bus's WiFi during his trip. If Biff makes $12/hour working online and has to pay $2/hour to access the bus's WiFi, how many hours long will the bus ride need to be for him to break even?

### Response:
 Kwanza hesabu ni kiasi gani Biff alitumia kujiandaa kwa safari: $11 + $3 + $16 = $<<11+3+16=30>>30
Sasa hesabu kipato cha neti cha Biff kwa saa baada ya kulipa kwa huduma ya WiFi kwa kutoa gharama ya WiFi kutoka kwa kiwango chake cha kila saa: $12/saa - $2/saa = $<<12-2=10>>10/saa
Hatimaye, gawanya pesa ambazo Bill alitumia na kiwango chake cha kila saa ili kujua masaa mangapi anapaswa kufanya kazi ili kufikia kiwango sawa: $30 / $10/saa = <<30/10=3>>3 masaa
