It takes 12 hours for a motorboat to travel a certain distance in still water, and 10 hours for an equal distance to travel along the current. It is known that the speed of the motorboat when it travels upstream is 24 kilometers per hour. What is the speed of the motorboat when it travels downstream?
汽艇在静水中行驶一定的距离需12小时，顺水行驶等距离需10小时，已知这汽艇逆水行驶时的速度是每小时24千米，求汽艇顺流时的速度是多少？
