There are two identical oil barrels, A and B, the A barrel is full of oil, and the B barrel is empty. Now pour oil from barrel A to barrel B at a certain speed, and (1/3) of the oil in barrel A is poured out in 6 minutes. According to this calculation, after a few minutes, there will be the same amount of oil in the two barrels of A and B?
有甲、乙两只相同的油桶，甲桶装满了油，乙桶是空桶．现在按照一定的速度从甲桶往乙桶倒油，6分时间倒出了甲桶油的(1/3)．照这样计算，再过几分后，甲、乙两只桶中的油一样多？
