例题：AEAS数学逻辑讲解（二）

　　AEAS数学推理打破了常规数学考试的形式，弱化了数字和公式，而是巧妙的将看似简单的运算与逻辑相结合，立体考察学生的思维逻辑。今天课窝考试网继续分享有关的例题讲解（二），和大家一起进步。

　　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.
