bamboo pole is less than 6 meters long. Xiaohua uses a meter ruler to measure from one end to 3 meters and make a mark A, and then measure from the other end to 3 meters and make a mark B. At this time, the distance between A and B is exactly the length of the pole. 20% of the bamboo pole, how many meters is the length of the bamboo pole?
一根竹竿不到6米长，小华用米尺从一头量到3米处作一个记号A，再从另一头量到3米处作一记号B，这时AB间的距离正好是竿长的20%，问竹竿长是多少米？
