A tortoise and a hare are running a race. They start from the same starting point at the same time, and when they reach a distance of 1500 meters from the starting point, they turn back and run back. The tortoise runs 20 meters per minute, and the rabbit runs 180 meters per minute. When the tortoise and the hare meet, how far is the tortoise from the turning point?
乌龟和兔子赛跑，它们同时从同一起点出发，当跑到距起点1500米处时就折返往回跑．乌龟每分钟跑20米，兔子每分钟跑180米．当乌龟和兔子相遇时，乌龟离折返点还有多少米．
