Question

Два студента напечатали вместе 36 страниц.Один печатал 1 ч,другой-2ч.Сколько страниц напечатал каждый,если скорость работы (производительность) у них одинаковая

Answer 1

1+2= 3 (ч) общее время
36:3=12 (стр/ч)
12*1=12 (стр) - один студент
12*2=24 (стр) - второй студент 

Answer 2

Problem Analysis

Two students printed a total of 36 pages. One student printed for 1 hour, while the other student printed for 2 hours. The productivity (work rate) of both students is the same. We need to determine how many pages each student printed.

Solution

Let's assume that the first student printed x pages and the second student printed y pages.

According to the given information, the total number of pages printed by both students is 36: x + y = 36 The first student printed for 1 hour, and the second student printed for 2 hours. Since their productivity is the same, we can assume that their work rates are equal. Therefore, the number of pages printed by each student is inversely proportional to the time they spent printing.

The work rate of the first student is x pages per hour, and the work rate of the second student is y pages per 2 hours. Since their work rates are equal, we can set up the following equation: x / 1 = y / 2

To solve this system of equations, we can use the substitution method. Let's solve the first equation for x: x = 36 - y Substituting this value of x into the second equation, we get: (36 - y) / 1 = y / 2

Now we can solve for y: 2(36 - y) = y 72 - 2y = y 72 = 3y y = 24

Substituting the value of y back into the equation x = 36 - y, we get: x = 36 - 24 x = 12

Therefore, the first student printed 12 pages and the second student printed 24 pages.

Answer

The first student printed 12 pages, while the second student printed 24 pages.
