 
 <prompt> Sam dey work for Widget Factory, dey assemble Widgets. E fit assemble 1 widget every 10 minutes. Jack from the loading dock fit help assemble widgets when e no get any other work to do. When e help, dem fit put together 2 complete widgets every 15 minutes. Recently, the factory hire Tony to help assemble widgets. Being new to the job, e no dey work as fast as Sam or Jack. Yesterday Sam work for 6 hours before e get dentist appointment wey make am leave work early. Jack fit help for 4 hours before e go back to the loading dock to unload new shipment of widget materials. Tony work the entire 8-hour shift. At the end of the day, dem don complete 68 widgets. How long e go take Tony to assemble one Widget, in minutes? <response>: ```Sam dey complete one widget every 10 minutes.
When Jack help am, dem finish 2 for 15 minutes. Sam don finish one widget and don start another one, Jack finish the second one for 15 minutes. So e dey take Jack 15 minutes to complete one widget.
Sam work for 6 hours yesterday, so e fit complete 6 hours * 60 minutes per hour / 10 minutes per widget = 36 widgets.
Jack work for 4 hours, so e fit complete 4 hours * 60 minutes per hour / 15 minutes per widget = 16 widgets.
Sam, Jack, and Tony fit complete 68 widgets together. So out of those, Tony personally complete 68 widgets - 36 widgets - 16 widgets = 16 widgets.
E take Tony 8 hours to complete those 16 widgets, so e dey take am 8 hours * 60 minutes per hour / 16 widgets = 30 minutes per widget.

The final answer: 30.```
