A and B travel from two places 36 kilometers apart. If a walks 2 hours ahead of B, they meet after B starts 2.5 hours; if B walks 2 hours ahead of a, they meet after a starts 3 hours. How many kilometers do a and B walk each hour?
Let the velocities of a and B be respectively X and Y km / h. according to the meaning of the question, we can get: (2.5 + 2) x + 2.5Y = 363x + (3 + 2) y = 36. The solution is: x = 6y = 3.6. The velocity of a is 6 km / h, and that of B is 3.6 km / h
There is a 200 digit number, each number is 3, divide it by 7
There is a 200 digit number, each number is 3, divide it by 7, what is the remainder? What is the number at the end of the quotient?
It's got to be formulas and results.
3 ÷ 7 = 0 more than 3
33 △ 7 = 4,5
333 ÷ 7 = 47,4
3333 △ 7 = 476 more than 1
33333 ÷ 7 = 4761 more than 6
333333÷7=47619
6 cycles 200 △ 6 = 33 remainder 2
The remainder is five and the quotient ends with four

This should be a math problem for grade one
Here is a triangle matrix
1 first row
-2.3 second row
-4 5 - 6 third row
7-8 9-10 row 4
.
(1) According to the law of the number matrix, what is the second number in line 8
(2) According to the law of the matrix, what is the number in the row of - 2012?
(3) In line 2013, how many are positive numbers? How many are negative numbers?
(1) Because there is a number in the first row of 1
-2 3 the second row - there are two numbers
-4, 5 - 6 the third row has three numbers
7 - 8, 9 - 10 the fourth row - there are four numbers
There are n numbers in row n
So there are 1 + 2 + 3 + 4 + 5 + ······ + n numbers from the first row to the n row. According to the summation formula of arithmetic sequence, s = Na1 + n (n-1) d / 2
Find s = (n square + n) / 2, that is, there are (n square + n) / 2 numbers in row n, and there are 28 numbers in row 7, which is also the number - 28. Then the first number in row 8 is 29, and the second number is - 30
(3) 1007 positive numbers and 1006 negative numbers
Because there are several (2012 square + 2012) / 2 numbers in 2012, that is 2025078, and the last number is - 2025078
So the 2013 line starts with an odd number, so the odd number of this line is 1007, that is, the positive number is 1007, and the even number is 1006, that is, the negative number is 1006
