People select news in expectation of a reward. This reward may be either of two kinds. One is related to what Freud calls the Pleasure Principle, the other to what he calls the Reality Principle. For want of better names, we shall call these two classes immediate reward and delayed reward.
In general, the kind of news which may be expected to give immediate reward are news of crime and corruption, accidents and disasters, sports, social events, and human interest. Delayed reward may be expected from news of public affairs, economic matters, social problems, science, education, and health.
News of the first kind pays its rewards at once. A reader can enjoy an indirect experience without any of the dangers or stresses involved. He can tremble wildly at an axe-murder, shake his head sympathetically and safely at a hurricane, identify himself with the winning team, laugh understandingly at a warm little story of children or dogs.
News of the second kind, however, pays its rewards later. It sometimes requires the reader to tolerate unpleasantness or annoyance — as, for example, when he reads of the threatening foreign situation, the mounting national debt, rising taxes, falling market, scarce housing, and cancer. It has a kind of “threat value.” It is read so that the reader may be informed and prepared. When a reader selects delayed reward news, he pulls himself into the world of surrounding reality to which he can adapt himself only by hard work. When he selects news of the other kind, he usually withdraws from the world of threatening reality toward the dream world.
For any individual, of course, the boundaries of these two classes are not stable. For example, a sociologist may read news of crime as a social problem, rather than for its immediate reward. A coach may read a sports story for its threat value: he may have to play that team next week. A politician may read an account of his latest successful public meeting, not for its delayed reward, but very much as his wife reads an account of a party. In any given story of corruption or disaster, a thoughtful reader may receive not only the immediate reward of indirect experience, but also the delayed reward of information and preparedness. Therefore, while the division of categories holds in general, an individual’s tendency may transfer any story from one kind of reading to another, or divide the experience between the two kinds of reward.

（1）在遇到问题：“钟面上，如果把时针与分针看作是同一平面内的两条线段，在2∶00~2∶15之间，时针与分针重合的时刻是多少？”时，小明尝试运用建立函数关系的方法：
①恰当选取变量x和y．小明设2点钟之后经过x min（0≤x≤15），时针、分针分别与竖轴线（即经过表示“12”和“6”的点的直线，如图1）所成的角的度数为y1°、y2°；
②确定函数关系．由于时针、分针在单位时间内转动的角度不变，因此既可以直接写出y1、y2关于x的函数关系式，也可以画出它们的图象．小明选择了后者，画出了图2；
③根据题目的要求，利用函数求解．本题中小明认为求出两个图象交点的横坐标就可以解决问题．
请你按照小明的思路解决这个问题．
（2）请运用建立函数关系的方法解决问题：钟面上，如果把时针与分针看作是同一平面内的两条线段，在7∶30~8∶00之间，时针与分针互相垂直的时刻是多少？
