流水问题是一类特殊的行程问题,有如下关系式:顺流速度=船在静水中的速度+水流速度,逆流速度=船在静水中的速度-水流速度.解题时注意应用“设而不求辅助量法”,五花八门的流水问题就可以迎刃而解了.
The flow problem is a special type of itinerary problem, which has the following relationship: downstream speed = ship speed in still water + water flow speed, countercurrent speed = ship speed in still water - water flow speed. No supplementary method is required," and a wide variety of problems can be easily solved.
