A boy is standing on a 19.6 m high bridge sees a motorboat approaching the bridge at a constant speed. When the boat is 27 m from the bridge, the boy drops a stone to the water below. If the stone strikes the water 3.0 m in front of the boat, at what speed is the boat traveling?

I got V = 12 m/s but I would like to know if it is correct so I know I'm on the right track for the rest of the problems.
