A person of 6 ft height wants to pluck a fruit that is hanging at one-fourth (1/4) the distance from the top of a 20 ft high tree. The person, standing 28 ft away from the tree, throws a stone which hits the top of the tree. He then moves towards the tree and, keeping the same angle of projection, throws another stone that now hits the fruit. Assuming the stones travel in a straight line from the hand to the target, what is the present distance of the person from the tree?
