To represent the distance John walked from the classroom before realizing he dropped the paper, start at 0 and move 35 units along the number line to the right. After realizing he dropped the paper, John has to walk back to get it. To represent John walking back to the paper, move 12 units along the number line to the left. Then, to represent the distance between the classroom and the spot where the paper fell, move 47 units along the number line to the left.
So, the distance John walked is 35 feet, the distance he walked back to pick up the paper is 12 feet, and the total distance between the classroom and the spot where the paper fell is 47 feet.
