There are two terminals A and B in a coastal area. It is known that a ship sails 300 kilometers per day from A to B, and 360 kilometers per day from B to A. 22 days, so how many kilometers is the distance between A and B?
某沿海地区甲、乙两码头，已知一艘船从甲到乙每天航行300千米，从乙到甲每天航行360千米，如果这艘船在甲、乙两码头间往返航行4次共22天，那么甲、乙两码头间的距离是多少千米？
