学校放五一长假,麦斯便和妈妈一起乘汽车去外婆家玩。汽车从郊外小站出发时,麦斯看见路旁里程碑上的里程数是个两位数(用AB表示),于是默默记下了出发的时间。汽车在公路上以恒定的速度前进。汽车开了1小时到达了一个新开发区,细心观察的麦斯发现路旁的里程碑上的数仍然是个两位数。 51 schools put the holiday, Max and her mother went to the Grandma's family car to play. When the car departed from the outskirts station, Max saw the mileage on the roadside milestone as a double digit (indicated by AB), so he silently recorded the starting time. The car advances at a constant speed on the road. The car arrived an hour later and reached a new development zone. Careful observation of Max's roadside milestone is still a double-digit number.
