Parallel World, Blue Planet.
==========
Title:
The two of them climbed the mountain. A reached the top of the mountain and B was still 400 meters away from the top. The speed of A and B descending the mountain was twice that of ascending the mountain. When A reached the bottom of the mountain, B was halfway up the mountain and asked,
How high was the mountain?
In a small but warm princess bedroom, a young man's brows were tightly knitted as he stared at the questions in the exercise book.
He was working hard to solve this question.
This young man was called Gu Bai, a first-year university student at Overgrown Forest University.
Gu Bai, who came from an ordinary family, chose to work part-time in his first year of university.
It was not serving plates or handing out flyers, but tutoring.
It was a 1v1.
Because he had no teaching experience, Gu Bai did not choose to teach middle school or high school. Instead, he chose a simple primary school.
Primary school tutoring?
Simple, easy, as long as you have hands
As a college student, Gu Bai was confident in teaching primary school students.
However…
However, the truth was out of Gu Bai's expectations.
The dimensional reduction attack did not happen. It was simple and easy. The feeling of having hands was not produced.
Instead…Gu Bai felt a little strained.
Of course, Gu Bai could solve it using an equation.
but... This was a primary school question. The primary school students in the sixth grade did not learn the one-dimensional multiple equations at all.
How could he talk about solving equations?
Facing this question, Gu Bai had no choice but to get serious again and change his train of thought.
His brain was working at high speed, thinking of various ways to solve the problem in front of him.
However…
Gu Bai was still helpless.
"I'm still a university student. Although I'm not from a famous university, would it be so difficult for me to solve primary school questions?”
"Did I go to a fake university?”
"Or is it that all the primary school questions are starting to be filled up?”
Gu Bai sighed, doubting his life.
"Teacher, I still have a question that I don't know how to answer.”
At this moment, Li Sisi handed the test paper over and pointed at another question on the test paper.
Gu Bai smiled as he looked at the question. He silently noted it down and stood up."Sisi, continue with the next question. Teacher drank too much water and needs to go to the toilet.”
After saying that, Gu Bai calmly stood up and walked towards the bathroom to ask Qiandu for help.
......
He closed the door.
Gu Bai washed his face with water to relax.
Damn, that was really embarrassing.
He didn't manage to reduce the dimensions and was instead overwhelmed by the elementary school questions.
You guessed it right. Gu Bai probably won't answer the second question that Li Sisi asked.
whew ~~
Taking a deep breath, Gu Bai composed himself.
The questions in primary school nowadays were really too complicated.
He wiped his hands with a tissue and did not waste any time. He immediately took out his phone and opened Qiandu. A and B climbed the mountain. A reached the top of the mountain and B was still 400 meters away from the top.
Instantly, many web pages popped up.
Just as Gu Bai was about to click on one of them to check it out.
A mechanical voice sounded in his mind.
"Ding, ding, ding."
" Binding the Super Teaching System."
"The Super Teaching System will definitely succeed."
Hearing the mechanical voice in his mind, Gu Bai was stunned for a moment before a hint of joy appeared on his face.
He had read novels before. Every night, he would read novels for a few hours before falling asleep.
Therefore, he was no stranger to the system.
After understanding the functions of the system, Gu Bai's eyes lit up.
The Super Teaching System, as the name implied, was for teaching.
However, based on Gu Bai's understanding of the system, he realized that the system was not as simple as teaching.
Not only did the system have the ability to give lessons, but it also had the ability to return lessons 100 times over.
Return what? The system didn't say anything.
Spirit pills? Gene serum?
It shouldn't be the case at the moment.
It was most likely related to the questions and knowledge.
Gu Bai was delighted when he understood.
He was not greedy. Although the system was not invincible, but…With this teaching system, it was only a matter of time before he became a super genius.
Gu Bai did not continue to study the system in depth. After reading the answers given by the netizens on Qiandu, he tidied his hair in front of the mirror and smiled faintly."The sea of stars of a top student starts from teaching elementary school students math problems."
.....................
"Teacher, why did you take so long to go to the toilet?”
As soon as she entered, she heard Sinead's voice.
At this moment, she raised her head and widened her eyes in suspicion."Teacher, did you go to Qiandu?”
"How is that possible?"
Gu Bai did not panic at all. He smiled calmly and said,"It's just a primary school question and I still need to use a thousand degrees. You're underestimating college students.”
He walked to Li Sisi's desk and pulled a stool to sit down. He habitually turned the pen and copied the draft.
"Come, look at the questions."
After saying that, Gu Bai quickly wrote and drew on the draft paper.
"The questions give the distance, speed, and time. From the questions, it's not difficult to tell that the time they used was the same.
Therefore, if the two of them walked for the same amount of time, the distance between them satisfied the relationship of " speed difference x time = distance difference ".
When they went up the mountain, A was 400 meters ahead of B. When going down the mountain, if A and B set off from the top of the mountain at the same time, because the speed of both of them doubled at the same time, the time taken by A to go down the mountain became half of the time taken to go up the mountain."The speed difference doubled, and the time became 1/2", so when A reached the foot of the mountain, A was still 400 meters ahead of B."
"Therefore, we can conclude that the distance up the mountain is 2400 meters, which means that the height of the mountain is 2400 meters.”
No matter what, Gu Bai was still a university student.
After seeing the answers on the Thousand Degrees, Gu Bai understood the logic behind the questions. He quickly sorted out the key points of the questions.
The key point of this mountain climbing question was that the time was the same. Using the speed ratio to obtain the distance ratio, and then find the mountain peak.
Soon, Gu Bai got the final answer. He smiled at Li Sisi and said,"The final result is 2400m. Isn't it very simple? Isn't it very easy?”
There's no way I'll be able to answer elementary school questions.
No, it's the door.
After solving this question, Gu Bai finally vented the unhappiness in his heart.
How could a college student like me be stumped by an elementary school question?
"This…" Li Sisi, who was sitting in her seat, was in disbelief. Her small mouth was slightly open, and her eyes were wide open.
Of course…It was not because Gu Bai had solved the question, but because she…
He understood.
