Abigail built 10 fences. Each fence took her 30 minutes to build. If she builds fences for the next 8 hours, how many fences would she have built in total?
8*60 = <<8*60=480>>480 minutes are in the next 8 hours.
Abigail builds 480/30 = <<480/30=16>>16 fences.
Abigail will have built 10+16 = <<10+16=26>>26 fences in total.
