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

### Instruction:
Jacob can write twice as fast as Nathan. Nathan wrote 25 letters in one hour. How many letters can the two write in 10 hours together?

### Response:
 Jacob anaandika barua 25*2 = <<25*2=50>>50 kwa saa moja.
Nathan na Jacob wanaandika barua 25 + 50 = <<25+50=75>>75 kwa saa moja.
Kwa pamoja wanaweza kuandika barua 75*10 = <<75*10=750>>750 kwa saa 10.
