178. 还有一题,读题花了点时间,其实看明白了很简单.求一个人从自己家到爹妈家的平均速度是不是在35和50之间. 1) From the nearest 100 miles, there are 300 miles from his house to his partents' house. 2) From the closest 1 hour, he spend 8 hours from his house to his partents' 好像是这样的,请参考楼下的思路,我的理解有误,虽然答案MS蒙对了. . 属于这个范围.选C 同第25题,如果题意是“以四舍五入到每100miles和1hour来计算的话”那么就是不确定,选E
以四舍五入到每100miles和1hour来计算的话, 300miles 可以选 250和349; 8 hours可以选 7.5和8.49
平均速度的范围:349/7.5----250/8.49==46.53--29.44, 不属于35-50。选E
