Find how long the person is in the air for first, and then use one of the basic kinematics equations to determine how far the person travels. It'll help to know that the time is only dependent on how far up vertically the person is from the ground, and the distance from the start point depends only on how far horizontally the person is from the swing (at equilibrium).
