A motorboat and a kayak both left pier X on a river and headed downstream, where the kayak moved at the speed of the river current, and the motorboat maintained a constant speed in still water. The motorboat reached pier Y downstream, then immediately turned and traveled back upstream, eventually meeting the kayak on the river 12 hours after leaving pier X. Calculate the number of hours it took the motorboat to go from X to Y.
