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

### Instruction:
Mike can type 65 words per minute. Due to a minor accident, Mike cannot use his right hand for a while so that his typing speed is now 20 words less per minute. If he is supposed to type a document with 810 words, how many minutes will it take him to finish typing the document?

### Response:
 Baada ya ajali, Mike anaweza kuandika maneno 65 kwa dakika - maneno 20 kwa dakika = <<65-20=45>>45 maneno kwa dakika.
Hivyo, ataweza kuimaliza kuandika hati hiyo katika maneno 810 / maneno 45 kwa dakika = <<810/45=18>>18 dakika.
