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

### Instruction:
 Bianca alifanya kazi kwa masaa 12.5 mwishoni mwa wiki iliyopita. Celeste alifanya kazi kwa mara mbili ya muda huo na McClain alifanya kazi masaa 8.5 chini ya Celeste. Watu hao 3 walifanya kazi kwa muda gani jumla?


### Response:
 Bianca = <<12.5=12.5>>12.5 masaa
Celeste = 2 * 12.5 = <<2*12.5=25>>25 masaa
McClain = 25 - 8.5 = <<25-8.5=16.5>>16.5 masaa
Jumla ya masaa = 12.5 + 25 + 16.5 = <<12.5+25+16.5=54>>54 masaa
Jumla ya dakika = 54 masaa * 60 dakika/masaa = <<54*60=3240>>3240 dakika
Watu hao 3 walifanya kazi kwa jumla ya dakika 3240.
