"america was different. america was a river roaring along, unmindful of the past. i could wade into this river, let my sins drown to the bottom, let the waters carry me someplace far." this quote from chapter 11 is said by whom? what does it reveal? what does this metaphor mean?

Explanation:

The quote is said by Amir.

Amir and Baba moved to America from Afghanistan. Amir hopes to erase and forget his past which is pain full and fierce. He is looking for something that can cover up all his past sorrows.

                      Amir symbolizes river to America and sees America as a fortune to forget all his guilt that he has committed in the past and move on in his life without his past haunting him. This is chance for him and Baba to start a new beginning a new life at America.

Amir thing and believes America like a river which flows and carries all his guilts and sins that he has committed in the past. River is always flowing and it ends at the ocean. Likewise the river is carrying and washing away all his past guilt and dumping it in the ocean which will again reflect back to him in the future. Thus America is temporarily for the meantime erasing all his past sins and AMir is moving on in his life with Baba.
