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

### Instruction:
 Sam anatumia dakika sitini kusoma Sayansi, dakika themanini kusoma Hisabati, na dakika arobaini kusoma Fasihi. Anatumia masaa mangapi kusoma masomo matatu?


### Response:
 Jumla ya dakika anazosoma masomo matatu ni 60 + 80 + 40 = <<60+80+40=180>>180 dakika.
Hivyo, jumla ya masaa anayotumia kusoma masomo matatu ni dakika 180 / dakika 60/saa = <<180/60=3>>3 masaa.
