　　AEAS是Australian Education Assessment Service, 澳大利亚教育评估服务机构的简称,成立于1985年，30年来一直致力于为准备进入澳大利亚初高中学习的国际学生提供高水平的综合性测试服务。今天小编为大家带来关于AEAS数学考试例题介绍，希望同学们掌握其中的运算和逻辑思维，下面就和小编一起看看吧.

　　Train A leaves Brisbane for Adelaide and travels at a constant speed. At the same time train B leave Adelaide for Brisbane and also travels at a constant speed.

　　Town X is between Brisbane and Adelaide. Brisbane, town X and Adelaide lie on a straight line. Which train has greater speed?

　　Which of following statements are sufficient to answer the question

　　Train B arrives at town X before train A.

　　Town X is farther to Brisbane than Adelaide

　　a.Statement I alone is sufficient to answer the problem

　　b.Statement II alone is sufficient to answer the problem

　　c.Statements I and II both are needed

　　d.Statements I and II both are not sufficient

　　火车A匀速从Brisbane驶向 Adelaide, 与此同时，火车B从Adelaide匀速驶向Brisbane.

　　小镇X在Brisbane和 Adelaide之间且 小镇X与Adelaide和Brisbane处于同一直线上。

　　附加以下哪个条件之后可以求出哪辆火车速度更快？

　　火车B比火车A先到达小镇X

　　小镇X离Brisbane比离Adelaide远

　　A 条件一

　　B 条件二

　　C 条件一和条件二

　　D条件一和条件二都不充分

　　Explanation：

　　Step 1

　　To conclude which train has lesser speed. We need two information i.e which train is relatively faster and position of town X.

　　Step 2

　　So, Statements I and II both are not sufficient to understand the problem clearly.

　　Step 3

　　Hence, d is the correct option.
