A child who fell into the river is drifting with a piece of wood. At point A, the child encounters a speedboat and a ship moving upstream, but due to the heavy fog, they are not noticed. 1 hour later, after learning about the child, both the speedboat and the ship immediately turn around to rescue. The time it takes for the speedboat to catch up from the moment it learns about the child is $\boxed{\text{hours}}$, and the time it takes for the ship to catch up from the moment it learns about the child is $\boxed{\text{hours}}$.
