If the length of a bamboo pole is less than 5 meters, measure 3 meters from one end and mark A, and then measure 3 meters from the other end and mark B. It is known that the distance between A and B accounts for (1/ 3), how many meters is the total length.
一根竹杆长度不足5米，从它的一端量出3米，标上记号A，再从另一端量出3米标上记号B，已知AB之间的距离占全长的(1/3)，全长多少米．
