Urgent! What should I do if I get a bad character after rebirth?

Other participating students also came out of the examination room one after another.

Some were smiling, but most were frowning.

"How did you solve this question?"

A classmate asked curiously, “On a map with a scale of 1:, the distance between points A and B is measured to be 25 centimeters.

If we want to draw a map of place A and place B on a map of 1: , how many centimeters should the distance between them be on the map? "

"10 centimeters!" Yunhe blurted out without thinking.

Zhou Hang was suddenly stunned when he heard this, and his heart was like a turbulent wave.

He looked at Yunhe in surprise, thinking: Isn't she just in the first grade of junior high school? How come she knows this?

So, he deliberately showed a puzzled look and asked Yunhe:

"Then can you tell me why it is 10 centimeters?"

Yunhe smiled slightly, with a confident light in his eyes.

She answered confidently:

"The first step is to use the scale formula

The distance on the map is equal to the actual distance multiplied by the scale. We can calculate that the actual distance between places A and B is: 25 multiplied by equals centimeters.

The second step is to draw on the map of 1:

The distance on the graph is: divided by equals 10 cm.

Therefore, when drawing the maps of places A and B on a 1: map, the distance between them should be 10 cm. "

Soon another student asked,

"It was a battle in World War I known as the 'Meat Grinder' and one of the most brutal and bloody battles in human history. Which battle is it?"

"The Battle of Verdun. The Battle of Verdun was the most destructive and longest battle in World War I. The fighting lasted from February 1916 to December 2, 21. Germany and France deployed more than 12 divisions, with more than 19 soldiers killed and more than 100 injured. It was called the Verdun meat grinder!"

Yunhe continued to speak slowly.

"I think this was covered in our history textbook, but I can't remember it so clearly. Oh, who knew that this quiz would be so detailed?" a classmate said in frustration.

"Isn't it? Compared with this classmate, I feel like I have a pig's brain. He actually remembers it so clearly." Another classmate continued.

When Yunhe saw that the situation was not good, he quickly ran away.

"Dear classmates, if we are destined to meet, we will meet in the finals. I have to hurry to catch the train. Goodbye!" After Yunhe said this, he ran faster than the rabbit's father.

Hailan bought train tickets for everyone for Sunday afternoon at 2 o'clock. After the exam, everyone returned to the hotel, had dinner, and then rushed to the train station.

The timing was just right. Not long after they arrived at the train station, it was time for their train to check in.

Everyone checked their tickets, entered the station, and got on the train.

They started asking Yunhe about the answers to other questions in today's exam, or the process of solving the problems.

Guan Yanqiu was still a little unconvinced, so he challenged Yunhe and said, "Yunhe, let me ask you a question!"

"Okay, go ahead and tell me. As a matter of course, I have to ask you a question later!" Yun He said provocatively without thinking.

"Then listen carefully, here is a chicken and rabbit cage problem and the answer:

"There are a number of chickens and rabbits in a cage. Counting from the top, there are 35 heads and counting from the bottom, there are 94 legs. How many chickens and rabbits are there?"

"It's too easy!" Yunhe shook his head gently and said with some disdain.

At this time, the other passengers on the train also became interested and wanted to see how the two students competed, so they all gathered around.

At this time, a conductor happened to pass by and knew that two students were participating in a high school competition. So he said to the passengers in the carriage, "Everyone, please sit in your seats and don't crowd together to block the aisle. If you are really interested, why don't you ask the two students if they are willing to come to the front of the carriage so that everyone can hear!"

"Okay, I'd be happy to do that. It'll be boring on the way back anyway!" Yunhe took the lead in agreeing.

"I don't care. Let's just have fun! Don't laugh at our little classmate. She is young and thin-skinned!" Guan Yanqiu said in a loud voice.

So the two of them followed the conductor to the front of the carriage, and Guan Yanqiu read the question again.

The carriage was very quiet at this time. Some people were waiting for Yunhe's answer, while others had already started thinking on their own.

Soon, everyone heard Yunhe's clear voice:

"Assuming that the cage is full of chickens, the number of legs is: 35*2=70 (pieces)

Less than the actual number of legs: 94-70=24 (legs)

这是因为把部分兔当成了鸡，每只兔少算了4-2=2条腿，所以兔的数量为：24/2=12（只）

The number of chickens is: 35-12=23 (chickens)

Therefore, there are 23 chickens and 12 rabbits. "

At this point, someone has already solved the answer using an equation.

He shouted to the two of them, "Yes, she is absolutely right."

Those passengers who are still confused are feeling frustrated and asking themselves why they are not even as good as a child.

"Okay, it's my turn!" Yunhe cleared his throat and asked loudly, "Excuse me, what is the medium-term numerical weather forecast system?"

"What the hell? I've never heard of this!" someone shouted.

Guan Yanqiu's face turned red. He had never heard of this before and didn't even know what Yunhe was talking about.

"Little classmate, can you please not come up with something that we can't understand at all? How about you come up with a question like the one that the classmate just asked, or even a riddle!" someone suggested.

"Student Guan Yanqiu, what do you think?" Yunhe shrugged, showing an indifferent and anything-goes expression.

"I, I don't know what system you are talking about." Guan Yanqiu replied dejectedly.

"Student Zhou Hang, do you know?" Yunhe began to ask questions.

Zhou Hang, who was suddenly called out, secretly groaned in his heart, "What does your competition have to do with me?"

He was so embarrassed that his face turned red. He grumbled for a long time before he said:

"I do not know either!"

“The medium-range numerical weather prediction system is a system that uses mathematical models and computer technology to predict weather conditions for a period of time in the future (usually 3 to 10 days).

It predicts weather changes by simulating and calculating the physical laws of atmospheric movement.

Our country has successfully developed a giant computer, the Galaxy-10, which can perform billion calculations per second.

This system is also developed based on this technology." Yunhe said.
