Xueba: The knowledge I teach, critical hits are returned

Parallel World, Blue Planet

========== topic:

【A and B are climbing a mountain. A reaches the top of the mountain, while B is still 400 meters away. A and B go down the mountain twice as fast as they went up. When A reaches the bottom of the mountain, B is halfway up the mountain. Question:】

【How high is the mountain?

In a small but warm"princess room" bedroom, the young man frowned and stared at the questions in the exercise book.....Trying hard to solve this problem.

This young man is called Gu Bai, a freshman at Linhai University.

Gu Bai, who came from a modest family, chose to work part-time in his freshman year.

Not serving dishes or handing out flyers, but tutoring.

It was a 1vs1 kind.

Because he had no teaching experience, Gu Bai did not choose to teach in junior high school or high school, but chose a simple elementary school.

Elementary school tutoring?

Simple, easy, easy, just have hands....

As a contemporary college student, Gu Bai was confident in teaching primary school students, and he was sure to achieve a dimensionality reduction attack.

However, the facts were beyond Gu Bai's expectations.

The dimensionality reduction attack did not happen, and the feeling of being simple and easy, and having hands to do it, did not occur.

Instead,...Gu Bai felt a little bit strenuous.

Of course, if he used the equation method, Gu Bai could solve it.

But...This is an elementary school question. 6th graders have not learned about polynomial equations.

How can they solve this problem with equations?

Facing this question, Gu Bai had to take it seriously again and change his mindset.

His brain was working at high speed, thinking of various ways to solve the question in front of him.

However,

Gu Bai was still helpless.

"After all, I am a college student. Even though I am not from a famous brand, would it be so difficult for me to deal with elementary school questions?"

"Could it be that I attended a fake university?"

"Or....Are the questions in primary schools now starting to become involuted?"

Gu Bai sighed and began to doubt his life.

"Teacher, I still have a question I don't know how to answer."

At this moment, Li Sisi handed over the test paper in her hand and pointed to another question on the test paper.

Gu Bai smiled and looked at the question, silently memorized it, then stood up and said,"Sisi, you continue to do the next question first. The teacher drank too much water and needs to go to the bathroom."

After that, Gu Bai calmly stood up and walked towards the bathroom to find Qiandu for help.......

Close the door.

Gu Bai washed his face with water and relaxed himself.

Oh my god, it was really embarrassing just now.

He failed to achieve dimensionality reduction attack, but was instead defeated by elementary school questions.

You guessed it right, Gu Bai might still not be able to answer the second question asked by Li Sisi....

Huhu~~

Gu Bai took a deep breath and gathered his thoughts.

The questions in elementary school are really too difficult nowadays. He dried his hands with a tissue and immediately took out his phone to open Baidu and searched: [A and B are climbing a mountain. A has reached the top of the mountain and B is still 400 meters away from the top of the mountain......】

Suddenly, many web pages pop up....

Just as Gu Bai was about to click on one to check, a mechanical voice came from his mind.

"Ding, ding, ding"

"Super teaching system is binding...."

"The super teaching system will definitely succeed."

Listening to the mechanical sound in his mind, Gu Bai was stunned for a moment, and then a hint of joy appeared on his face.

He had read novels, and he would read for several hours every night before falling asleep.

So he was not unfamiliar with the system.

After understanding the functions of the system, Gu Bai's eyes lit up.

The super teaching system, as the name suggests, is for teaching.

However, according to Gu Bai's simple understanding of the system just now, he found that the system is not as simple as teaching.

The system not only has the teaching ability blessing buuf, but also has the function of returning a hundred times the teaching.

What is returned? The system does not explain it.

Panacea? Gene medicine?

It should not be at present.

It is probably related to the topic and knowledge.

After Gu Bai figured it out, he was happy.

He is not greedy. Although the system is not directly invincible,...With this teaching system, it is only a matter of time to become a super academic master by teaching little by little.

Gu Bai did not continue to study the system in depth. After reading the answers to the questions given by netizens on Baidu, he adjusted his hair in front of the mirror and smiled faintly:"The starry sea of academic masters starts with teaching elementary school students math problems."....".....................

"Teacher, why did you take so long in the toilet?"

As soon as I entered the room, I heard Li Sisi's voice.

At this time, she raised her head and widened her big eyes and asked suspiciously:"Teacher, you didn't go to Qiandu, did you?"

"How is that possible?"

Gu Bai, who was hit on the head, was not panicked at all. He smiled calmly and said,"I'd use a thousand degrees to answer a primary school question. You underestimate college students." He walked to Li Sisi's desk, pulled a stool and sat down. He habitually turned the signature pen, copied the draft and said:

"Come, look at the questions."

After saying that, Gu Bai quickly wrote and drew on the draft paper.

"The quantities given in the question include distance, speed, and time. It is not difficult to infer from the question that the time they took is the same.

Therefore, when the two people walk for the same time, the distance between them satisfies the relationship of"speed difference × time = distance difference".

When going up the mountain, A is 400 meters ahead of B. When going down the mountain, if A and B start from the top of the mountain at the same time, since the speeds of both people double at the same time, the time it takes for A to go down the mountain becomes half of the time it takes to go up the mountain."The speed difference doubles and the time becomes 1/2", so when A reaches the foot of the mountain, the distance A leads B is still 400 meters......"

"......Therefore, in the end, it can be concluded that the distance up the mountain is 2400 meters, that is, the height of the mountain is 2400 meters."

After all, Gu Bai is also a contemporary college student.

After seeing the answer given on the thousand-degree website and understanding the logical points of the problem, Gu Bai quickly sorted out the key points of the problem.

The key point of this mountain climbing problem is that the time is the same, and the speed ratio is used to obtain the distance ratio, and then the height of the mountain is calculated.

Soon, Gu Bai found the final answer. He smiled and looked at Li Sisi and said,"The final result is 2400m. Isn't it very simple? Isn't it very easy? Is it okay as long as you have hands?""

The elementary school problem wants to roll me, there is no way.

No, the door is welded for you.

After solving this problem, Gu Bai's unhappiness in his heart just now was finally vented.

Can a college student like me be stumped by an elementary school problem?

"this..."

Li Sisi, who was sitting in her seat , was a little unbelievable, her mouth slightly opened, and her eyes widened....It's not because Gu Bai solved the problem, but because of her...

I understand.
