After school in the afternoon, my younger brother walked home at a speed of 40 meters per minute. Eight minutes later, my elder brother also walked home from school at a speed of 60 meters per minute. As a result, the two arrived home at the same time (neither of them stayed on the road). How far is their home from the school?
下午放学时，弟弟以每分钟40米的速度步行回家．8分钟后，哥哥以每分钟60米的速度也从学校步行回家，结果两人同时到家(路上两人都没逗留)．他们家距学校多少米．
