Chapter 132 Difficult math problem!Do you know?
Not only Tang Wan, but also the students around him voiced doubts one after another, and no one even looked down on Zhang Fan.
For them, for a person with Zhang Fan's identity, it is more of a sense of distance and fear. The so-called awe, and even any respect, all come from instinctive fear.
"I'm dying of laughter. I didn't expect Young Master Zhang would really agree to compete in math with Four-eyed Frog Boy!"
"I guess Young Master Zhang doesn't know about Four-Eyed Frog Boy, but he won the first prize in a national competition in mathematics!"
"This wave, this wave is called bad luck for myself. This time Young Master Zhang is going to make a fool of himself. We have to hold back when the time comes, and don't laugh too loudly. It hurts his self-esteem!"
"What are you afraid of? Young Master Zhang said a long time ago that he won't use his status to suppress our rich second generation. He always speaks the same words. When the time comes, I must laugh at him severely and make him lose face!"
"That's right, what this classmate said is right, I will also ruthlessly laugh at First Young Master Zhang, and let him know what it means to fall from the high clouds to the bottom!"
"Count me in, hahahaha!"
……
All of a sudden, the students around laughed and questioned, but Zhang Fan didn't put these people in his eyes and ignored them.
As for Logan who was on the side, she also heard the mocking words around her, so she continued to ask Zhang Fan worriedly.
Facing Logan's worry, Zhang Fan smiled lightly and waved his hands casually.
"Don't worry, I still have great confidence in myself when it comes to mathematics. I can hang him up and beat him with one hand!"
Seeing Zhang Fan's confident appearance, Tangwan didn't ask any more questions, because he knew that if Zhang Fan said yes, it was true.
Because in Logan's eyes, Zhang is such a mysterious man.
Strong and confident.
Soon Four-eyed Frog Boy wrote down the math problem on the blackboard that he wanted Zhang Fan to solve!
【It takes 250 seconds for a train to pass through a 25-meter-long tunnel, and 210 seconds to pass through a 23-meter-long tunnel. If the train meets another train with a length of 150 meters and a speed of 72 kilometers per hour, how many minutes will it take to pass by the wrong train?】
Looking at the topic on the blackboard, everyone in the classroom let out exclamations of wonder.
"My God, it's actually the legendary Olympiad!"
"It's so amazing, I can't figure out the principle of the Olympiad at all. I didn't expect the four-eyed frog boy to come here at random, which is a piece of Olympiad problem!"
"Yeah, just looking at the title, I can't understand what he wants to express. In short, it's just that the sentence looks awesome!"
"This wave, this wave, I guess Young Master Zhang can't solve this kind of problem at all, normal people wouldn't study him!"
……
All of a sudden, everyone in the classroom began to question Zhang Fan's ability.
Even the four-eyed Frog Boy beside him was very disdainful, he threw the chalk, and then said to Zhang Fan extremely arrogantly.
"It's your turn, Young Master Zhang, come up and solve my problem. If you can't solve it, you can apologize to all of us now, and we can forgive you!"
Four-eyed Frog Boy looks like I'm doing it for your own good to avoid embarrassing you on stage, which makes people want to beat him up very much.
However, looking at such a simple topic, Zhang Fan smiled disdainfully.
"Are you insulting my IQ by asking such a simple question? Let alone me, even readers of this book can solve it!"
Zhang Fan stepped forward quickly, picked up the white chalk in the chalk box, and began to write.
[The train passing through the tunnel refers to the time when the front of the train enters the tunnel and the end of the train leaves the tunnel. Therefore, the distance traveled by the train in this process is equal to the length of the train plus the length of the tunnel.
首先我们可以先求出列车的速度(250-210)÷(25-23)=20(米/秒)，由于我们已经知道路程等于车长加隧道长，
那么这个列车的车长为20×25-250=250(米)，在这里我们有一个单位的换算，72千米化为米：72000÷3600=20(米/秒)
所以两车的错车时间为(210+250)÷(20+20)=400÷40=10(秒)】
"So the time the two cars missed is 10 seconds!"
Zhang Fan threw the chalk casually, turned around, and looked at the four-eyed Frog Boy in front of him with disdain, as if mocking the simplicity of his question.
"What, this is impossible!"
Seeing that Zhang Fan really solved his problem, the four-eyed frog boy in front of him made a voice of disbelief.
Even the students around were shocked.
"My God, Young Master Zhang actually solved the problem that the four-eyed frog was asking. This is the end!"
"Damn it, why does Young Master Zhang actually know the Olympiad? It doesn't make sense at all. Isn't he the eldest son of the family? Logically, there is no need to learn such things!"
"You said it was you, and I don't understand. Shouldn't this kind of rich second-generation young and old start learning how to run a family business early? Why would they learn this kind of seemingly nonsensical business that has no social practice help?" What about the Olympiad?"
……
All of a sudden, there were wailing expressions in the entire classroom.
Obviously they were completely shocked by Zhang Fan's operation.
With their small brains, they can't figure out why this is.
Although the four-eyed frog boy on the podium was trembling slightly at the moment, he quickly calmed down because he hadn't completely lost the duel yet.
Yes, it's just that Zhang Fan's sister came up with his problem. If he can solve Zhang Fan's problem, then this round will be considered a draw!
I haven't lost yet, and it's not time to despair!
As expected, the four-eyed frog boy regained his composure and regained his confidence. He looked at Zhang Fan calmly and said slowly.
"Come on, Young Master Zhang, it's your turn to ask questions!"
Looking at the confident and indifferent four-eyed frog, Zhang Fan picked up the blackboard eraser, silently erased the scribbled questions in front of him, and then began to write a math problem he had prepared for him.
[There are 3 people going to stay, 30 yuan a night.
Each of the three people paid 10 yuan to make up 30 yuan and gave it to the boss. Later, the boss said that only 25 yuan is enough for today's discount.
He took out 5 yuan and ordered the waiter to return it to them, but the waiter secretly hid 2 yuan.
then.
Distribute the remaining 3 yuan to the three people, and each person gets 1 yuan.
In this way, each person paid 10 yuan at the beginning, and now 1 yuan is returned, which is 10-1=9.
It only cost 9 yuan per person, 3 people 9 yuan each, 3 X 9 = 27 yuan + 2 yuan hidden by the waiter = 29 yuan.
Where did the other dollar go? ? ? 】
After finishing writing the topic, Zhang Fan also imitated the four-eyed frog boy, threw the chalk casually, and said to him.
In the meantime, Zhang Fan still did not forget to show a condescending and mocking look.
"Come on, it's your turn to solve the problem!"
