Xiao Ming's home is 9,600 meters away from school, and it takes half an hour to ride to school every day. He first went through a 3600-meter uphill road, which took 18 minutes, and the rest was downhill. If you keep this speed, ask Xiao Ming how long it will take to ride home after school every day?
小明家到学校共9600米，每天骑车上学共需要半个小时．他先经过一段3600米的上坡路，用了18分钟，余下的是下坡路．若保持这样的速度，问小明每天放学后骑车回家需要多少时间？
