Question

Две бригады паркетчиков работают с одинаковой производительностью.Первая бригада работала 16ч,вторая-36ч и уложила на 2160 дм квадартныхпакета больше.Сколько квадратных дециметров паркета уложила каждая бригада?

Answer 1

1) 36 - 16 = 20(ч) разница во времени
2) 2160 : 20 = 108( дм/ч) производительность
3) 108 х 16 = 1 728( дм²) уложила первую бригада
4) 108 х 36 = 3 888(дм²) уложила вторая бригада
                Ответ: 1 728 дм² первая бригада уложила
                            3 888 дм² вторая бригада

Answer 2

1) 36 - 16 = 20 ч -  вторая бригада больше работала 
2) 2160 : 20 = 108 кв.дм - укладывается в один час
3) 108 * 16 = 1728 кв.дм -  уложила 1-вая бригада 
4) 1728+2160=3888 кв.дм -  уложила 2-рая бригада

Answer 3

Problem Analysis

We are given two teams of parquet installers who work at the same productivity rate. The first team worked for 16 hours, while the second team worked for 36 hours and installed 2160 square meters more parquet than the first team. We need to determine how many square decimeters of parquet each team installed.

Solution

Let's assume that the productivity rate of each team is P square meters per hour.

The first team worked for 16 hours, so the total amount of parquet they installed can be calculated as: Amount of parquet installed by the first team = P * 16

The second team worked for 36 hours, so the total amount of parquet they installed can be calculated as: Amount of parquet installed by the second team = P * 36

According to the problem, the second team installed 2160 square meters more parquet than the first team. Therefore, we can set up the following equation: Amount of parquet installed by the second team = Amount of parquet installed by the first team + 2160

Substituting the above expressions, we get: P * 36 = P * 16 + 2160

Simplifying the equation, we have: 20P = 2160

Solving for P, we find: P = 2160 / 20 = 108 square meters per hour

Now that we know the productivity rate of each team, we can calculate the amount of parquet installed by each team.

The amount of parquet installed by the first team is: Amount of parquet installed by the first team = P * 16 = 108 * 16 = 1728 square meters

The amount of parquet installed by the second team is: Amount of parquet installed by the second team = P * 36 = 108 * 36 = 3888 square meters

To convert these values to square decimeters, we multiply by 100: Amount of parquet installed by the first team in square decimeters = 1728 * 100 = 172800 square decimeters

Amount of parquet installed by the second team in square decimeters = 3888 * 100 = 388800 square decimeters

Therefore, the first team installed 172800 square decimeters of parquet, while the second team installed 388800 square decimeters of parquet.

Answer

The first team installed 172800 square decimeters of parquet, while the second team installed 388800 square decimeters of parquet.
