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

### Instruction:
 Barbara Blackburn anaweza kuandika maneno 212 kwa dakika. Kutokana na sindano ya carpal, Barbara hawezi kutumia mkono wake wa kushoto kwa muda fulani hivyo kasi yake ya kuandika sasa ni maneno 40 chini kwa dakika. Ikiwa anatakiwa kuandika hati yenye maneno 3440, itamchukua muda gani kumaliza kuandika hati hiyo?


### Response:
 Kutokana na sindano ya carpal, Barbara anaweza kuandika maneno 212 - 40 = <<212-40=172>>172 kwa dakika.
Hivyo, ataweza kumaliza kuandika hati hiyo kwa dakika 3440/172 = <<3440/172=20>>20.
