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

### Instruction:
Sam works at the Widget Factory, assembling Widgets. He can assemble 1 widget every 10 minutes. Jack from the loading dock can help assemble widgets when he doesn't have anything else to do. When he helps, they put together 2 complete widgets every 15 minutes. Recently the factory hired Tony to help assemble widgets. Being new to the job, he doesn't work as fast as Sam or Jack. Yesterday Sam worked for 6 hours before he had to leave work early for a dentist appointment. Jack was able to help out for 4 hours before he had to go back to the loading dock to unload a new shipment of widget materials. Tony worked the entire 8-hour shift. At the end of the day, they had completed 68 widgets. How long does it take Tony to assemble a Widget, in minutes?

### Response:
 Sam anakamilisha widget kila baada ya dakika 10.
Wakati Jack anasaidia, wanakamilisha 2 katika dakika 15. Sam amekamilisha widget 1 na ameanza kufanya kazi kwenye nyingine, na Jack anamaliza ya pili dakika ya 15. Kwa hivyo inamchukua Jack dakika 15 kukamilisha widget.
Sam alifanya kazi kwa masaa 6 jana, kwa hivyo alikuwa na uwezo wa kukamilisha 6 masaa * dakika 60 kwa saa / dakika 10 kwa widget = <<6*60/10=36>>36 widgets.
Jack alifanya kazi kwa masaa 4, kwa hivyo alikuwa na uwezo wa kukamilisha 4 masaa * dakika 60 kwa saa / dakika 15 kwa widget = <<4*60/15=16>>16 widgets.
Sam, Jack, na Tony walikuwa na uwezo wa kukamilisha widgets 68 kwa pamoja. Kwa hivyo kati ya hizo, Tony alikamilisha widgets 68 - 36 widgets - 16 widgets = <<68-36-16=16>>16 widgets binafsi.
Ilimgia Tony masaa 8 kukamilisha widgets hizo 16, kwa hivyo anachukua masaa 8 * dakika 60 kwa saa / 16 widgets = <<8*60/16=30>>30 dakika kwa widget.
