A woman on a bridge 104 m high sees a raft floating at a constant speed on the river below. She drops a stone from rest in an attempt to hit the raft. The stone is released when the raft has 7.39 m more to travel before passing under the bridge. The stone hits the water 2.71 m in front of the raft. Find the speed of the raft.
