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

### Instruction:
 Fernanda alinunua vitabu vya sauti sita kutoka Audible ili kusikiliza kupitia programu yake ya Audible. Ikiwa kila kitabu cha sauti kilikuwa na masaa 30 na alisikiliza masaa 2 ya kitabu kimoja kila siku, hesabu muda jumla uliomchukua kumaliza vitabu vyote sita?


### Response:
 Ili kumaliza kitabu cha sauti cha masaa 30, kwa kusikiliza masaa 2 ya kila kitabu kila siku, Fernanda alichukua masaa 30 / 2 masaa/siku = <<30/2=15>>15 siku kumaliza kitabu kimoja.
Ikiwa alinunua vitabu vya sauti sita, idadi jumla ya siku itakayomchukua kumaliza vitabu vyote ni vitabu vya sauti sita * 15 siku/kitabu cha sauti = <<6*15=90>>90 siku.
