An Olympic math problem,
If you increase the speed by 20%, you can arrive one hour earlier than the original time. If you arrive at the original time by one hour, if you arrive at the original speed by 120 km, you can arrive 40 minutes earlier. How many meters is the distance between a and B? Please use the general solution instead of the equation
If the speed is increased by 120%, then the ratio of the speed to the original speed is 6:5, then the time ratio of the journey is 5:6, that is, 1 / 6 less than the original time

An Olympic math problem in primary school
A and B do math problems together. If a does four more problems as much as B does, if B does six more problems, that's three times as much as a does. How many problems does a do? How many problems does B do? How many problems do B do
According to the meaning of the question, B does 4 more questions than a
If B does 6 more questions than a: 4 + 6 = 10, which is 3 times of A
So a is: 10 / [3-1] = 5 questions
B: 5 + 4 = 9
I'm a little confused ~ 10 / (3-1) = 5, which one - 1 ~ he said it's three times at this time ~ that should be 10 / 3~
If B does 6 more questions than a: 4 + 6 = 10,
It's three times as much as a, more than a
3-1 = 2 times
A did it
10 △ 2 = 5 questions
B did
5 + 4 = 9 questions
A primary school Olympic math problem: in the number 1 to 200, the number "1", a total of how many times
There are many formulas: if n is a single digit: n > 1, then the number of 1 is 1. If n (represented by Mn) is a ten digit: 11 * 1 + m (where n > 1, if n < 1, then 11) if n (represented by Kmn) is a hundred digit: when k = 1, M = 0:20 + N + 1 (where n > 1, if n < 1, then 21) when k
After adding the same number to the numerator and denominator of 8 / 15, it will be divided into 9 / 10?

80+10x=135+9x
x=55
The emperor will give wine to the minister. The wine given to the second grade minister is one-half of the first grade minister, the wine given to the third grade minister is one-third of the first grade minister, the wine given to the fourth grade minister is one-quarter of the first grade minister, the wine given to the fifth grade minister is one-fifth of the first grade minister, the wine given to the sixth grade minister is one-sixth of the first grade minister, and the wine given to the seventh grade minister is one seventh of the first grade minister, How many bottles of wine must the emperor prepare?
The least common multiple of 234567 is 420, which is the wine of the Minister of one grade. If you know one grade, you can ask for the rest. Two grades: 420 * 1 / 2 = 210 (bottles), three grades: 420 * 1 / 3 = 140 (bottles), four grades: 420 * 1 / 4 = 105 (bottles), five grades: 420 * 1 / 5 = 84 (bottles), six grades: 420 * 1 / 6 = 70 (bottles), seven grades: 420 * 1 / 7 = 60 (bottles) add up to 4
There are 100 monks eating 100 steamed buns. If the big monk eats 3 steamed buns per person and the little monk eats 1 steamed bun per 3 people, then the big monk has ()
A. 20 people B. 25 people C. 30 people D. 35 people
Suppose the great monk has x people. According to the meaning of the question, we get 3x + 100 − X3 = 100. The solution is: x = 25
Xiao Ming does natural number addition, such as 1 + 2 + 3 + 4 + 5 ~ the final sum is 888
Later, I found that I accidentally added one more number. I asked which natural number was added?
（1+2+3+4+5~~~40）＝820
（1+2+3+4+5~~~41）＝861
（1+2+3+4+5~~~42）＝903
We can see that it is added to 41, and then 888-861 = 27
