Chapter 1243 The Matter Of Two People Building A Nest
two people nesting thing
Of course Chen Yi knew that Wuming was referring to Lin Xinting. She has never even learned fractions, so it must be very difficult to calculate.
"It's just luck." Chen Yi forced a smile, but he was worried about Lin Xinting in his heart.
"Then I'll ask the next question." Wuming said quickly.
"Feng has something to discuss with Huang from Qixian Star to Tianling Star. The distance between the two stars is 18 million miles. Feng can fly two thousand miles with one flap of his wings, and three thousand miles with one flap of Phoenix. The two of them The frequency of flapping the wings is the same, every second."
"When the phoenix departs from the Qixian star, the phoenix also flies from the Tianling star to the Qixian star. Whenever she meets Feng, she returns to the Tianling star, and when she arrives, she goes to the Qixian star again, and so on."
"Then!" Wuming's voice rose 220 times in an instant, "When the phoenix reached the Heavenly Spirit Star, how far did the phoenix fly in total?"
What a proud phoenix... Chen felt silent mourning for that phoenix. He was obviously a noble and strong man, but he lived like a licking bird.
"Twenty-seven million miles." Chen Yi replied without hesitation, "Of course, if you want to consider the actual situation, such as the time it takes for the phoenix to adjust the direction, decelerate and accelerate, the answer is slightly less than this number."
"Very good!" Wuming said happily, "Can you tell me how you calculated it?"
"It's very simple. The flight time of the phoenix is fixed and equal to the flight time of the phoenix. That is to say, the ratio of the flight distance of the phoenix and the phoenix is equal to the ratio of the speed of two people."
"Of course," Chen Yi added, "if you want to use the method of taking the limit of the sum function, you can also solve this problem.
"No need!" Wuming said happily, "Your talent is really good. You have such a strong comprehension of arithmetic without being taught by anyone. Unlike others, all calculations are done by hard calculation. I am very optimistic about it." you."
"Hehe..." Chen Yi smiled awkwardly. He can't say that there is a little spirit teaching beside him, and he was tortured to death by these questions before.
Judging from Xiao Ling's tone of hating iron for nothing, he really doesn't have any "talent".
"Listen well, the next question." Wuming watched Chen Yi's eyes more and more fondly, which made him feel a little guilty.
"It turned out that Feng was looking for Huang to discuss the two of them building a nest. Feng and Huang needed twelve and fifteen years to build a nest alone."
"The two have been working together for five years. At this moment, Huang has something to leave."
"May I ask how long it will take Feng to build the nest alone? If Feng and Huang have a clear division of labor, cooperate tacitly, and don't fish in troubled waters, four years." Chen Yi answered directly.
His first feeling was: Why did the nest take so long to build? His second feeling was: I didn't expect him to blame the phoenix, and he really licked the bird until the end. The third feeling is: Huang is still so lazy, at this time, he has to give up his picks.
"Perfect!" Wuming laughed loudly, it's a pity that you are not my disciple.
"I'm also sorry." Chen Yi said modestly. But what he thought in his heart was that if there was a real competition in this aspect, it would not be certain who would be the teacher.
"In order to win Huang's favor, Feng found a lot of Lianshi and Liquan for her. Four Lianshi weighs four catties more than three Liquan, and eight Liquan weighs one catty more than nine Lianshi. Excuse me for one Lianshi and Liquan. How much does each Liquan weigh?"
"A portion of Lianshi seven catties, a portion of Liquan eight catties."
"If Huang drinks 2,000 catties of Liquan every day, he will finish drinking it two days earlier than the expected time. If he drinks 1,500 catties a day, he will finish drinking it two days later than the expected time.
How much is it?"
"Twenty-four thousand catties."
"Because I was bored, Huang caught some double-headed sparrows and blue crystal rabbits. Among them, the double-headed sparrows had two heads and two legs, and the blue crystal rabbits had one head and four legs. She found a total of twenty-six heads and sixty-two legs. May I ask how many two-headed sparrows and blue crystal rabbits there are?".
