Xiaoming walks to school, if he increases the speed by 25%, he can arrive 10 minutes earlier than the original time, if he drives 800 meters at the original speed, and then increases the speed by 50%, he can arrive 10 minutes earlier than the original time. How far is it from school?
小明歩行去上学，如果把速度提高25%，那么可比原定时间提早10分钟到达，如果以原速行驶800米后，再将速度提高50%，则比原定时间可提前10分钟，小明家离学校多远？
