The distances from point A to point B along the river and along the stream are the same and equal to 1 km. The speed of the current in the stream is $V$ km/h, and in the river it is $(2V + 1)$ km/h. The current in both the river and the stream flows from A to B. If the difference in time taken by the boat to travel from B to A and back along the stream is added to the time taken by a raft to travel from A to B along the river, the total is exactly 1 hour. By how many kilometers per hour is the speed of the boat greater than the speed of the current in the stream? The value of $V$ is not given. The answer should be a number.
