smj听力初二

途中汽车转向2次，将时间分为abc3段
设汽车在离校x米处折返,可得一下关系
40a=x
(40+8)b=x-8a
8(a+b)+40c=100
x+8(b+c)=100
要同时到达显然两批人乘车的时间应该相等，即a=c
可以解得a=c=15/8,b=5/4,x=75
共用时t=a+b+c=5小时
所以在11点出发

人人人人人人人人人人人人人人人人人人人人人人人人人人人人人人人人人人人人人人人

求人不如求己，加油！
学习是自己的事，你可以要别人帮你做作业，但不要期待这样做会提高自己的学业成绩。望你三思！

这个不用担心的，等你考试考完后，必然会得到很多的学校详细资料。

初三的开学考试肯定是考初二的啦,难免有一两道“选择题”是初一的作为送分题!如果是开学考试的话,关键还是想测测大家的底子,然后再编班吧(单单编班的话,看初二毕业试成绩不就好了)?如果连班都分配好了的,那么这次考试很多余. 还有!你们才初二毕业,一开学就考初三的内容(太不实际,举措多余)?要是能考个优秀及格,那还用再花一年的光阴去“复读”么? 正解是初二的题目占98%初一的占2%.
