Crossing The River

Two brothers come to a river. There is a boat, however, it can only carry one of them. How do they each get to the other side of the river using the boat assuming neither of them know how to swim?

    One guy on each side of the boat (in the water), holding on. They use their other arm as to paddle.

    Not quite as that would count as 2 people

    They could tie the boat to the side of the river they are on and once one brother gets to the other side, the other can pull the boat back using the rope. Then he can get to the other side as well.

    One brother uses the boat to go to side B; he will either use the boat back to side A or he will find someone else to get the boat back to side A. The 2nd brother will then be able to go to side B.

    Do we assume they come to the river on the same side? If not, then we one brother crosses to other other side, then the other brother gets into the boat and crosses too. Do they need to remain on the other side of the river? If not, then one brother crosses and returns, then the other brother crosses. Both brother will have gone to the other side.

    not quite a logical puzzle as the solution hinges on assumptions outside of the text or clever tricks of language.
