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

### Instruction:
A leaf is being blown down a sidewalk by swirling gusts of wind. For every five feet that a gust blows it forward, the wind swirls and blows it back two feet. How many feet has it traveled down the sidewalk after 11 gusts of wind?

### Response:
 Kila mzingo wa upepo unalisukuma jani mbele kwa futi tano, hivyo mzingo wa upepo 11 utalisukuma mbele kwa futi 5 * 11 = <<11*5=55>>55.
Kila mzingo wa upepo unalisukuma jani nyuma kwa futi mbili, hivyo mzingo wa upepo 11 utalisukuma nyuma kwa futi 2 * 11 = <<11*2=22>>22.
Kwa kuwa jani linasukumwa mbele na nyuma kwa kila mzingo wa upepo, umbali wa mwisho baada ya mzingo wa upepo 11 ni 55 - 22 = <<55-22=33>>33 futi.
