The starting fare of taxis in Beijing is 10 yuan within 33 kilometers, and 2 yuan per kilometer after 1 kilometer. When the mileage exceeds 15 kilometers, the excess part is 3 yuan per kilometer. Both Xiaoyue and Dongdong took taxis home from the amusement park. Xiaoyue spent 23 yuan more than Dongdong. May I ask: How many kilometers is the farthest distance from Xiaoyue's home to the amusement park? (less than 1 kilometer is counted as 1 kilometer, assuming that there are no traffic lights and no traffic jams on the way home for the two of them)
北京市出租车的起步价是33公里以内10元，公里后按每公里2元计费，当里程超过15公里后，超出部分按每公里3元计费．小悦、冬冬两人都从游乐园分别坐出租车回家，小悦比冬冬多花了23元，请问：小悦家距离游乐园最远是多少公里？(不足1公里按1公里计，假定两人回家一路上没有红绿灯，也没有堵车)
