Question

Две тракторные бригады вспахали вместе 762 га поля. Первая бригада работала 8 дней и вспахивала за день 48 га. Сколько гектаров поля вспахивала за день вторая бригада если она работала 9 дней? Какая бригада вспахивала больше и на сколько

Answer 1

1 бригада - 48 га*8 дней=384 га 2 бригада - 762 га-384 га=378 га за 9 дней 378/9 =42 га за один день.

Answer 2

Вычислим сколько вспахала 1 бригада
48*8=384 (га)
Вычислим сколько вспахала 2 бригада
762-384=387 (га)
Вычислим сколько вспахивала за 1 день 2 бригада
387:9=42 (га)
Вычислим разницу
48-42=6(га)

Ответ:42 га в день вспахивала 2 бригада; на 6 га больше вспахивала 1 бригада в день,чем 2 бригада

Answer 3

Calculation of Hectares Plowed per Day by the First Brigade

To determine how many hectares of the field the second brigade plowed per day, we first need to calculate the average hectares plowed per day by the first brigade.

The first brigade worked for 8 days and plowed a total of 48 hectares. To find the average hectares plowed per day, we divide the total hectares by the number of days:

Average hectares plowed per day by the first brigade = Total hectares plowed / Number of days worked

Average hectares plowed per day by the first brigade = 48 hectares / 8 days = 6 hectares per day .

Calculation of Hectares Plowed by the Second Brigade

Now that we know the average hectares plowed per day by the first brigade, we can calculate the total hectares plowed by the second brigade.

The second brigade worked for 9 days. Let's assume they plowed x hectares per day. The total hectares plowed by the second brigade can be calculated as follows:

Total hectares plowed by the second brigade = Number of days worked * Hectares plowed per day

Total hectares plowed by the second brigade = 9 days * x hectares per day

Since we know that the two brigades together plowed a total of 762 hectares, we can set up the following equation:

Total hectares plowed by the first brigade + Total hectares plowed by the second brigade = Total hectares plowed

48 hectares + 9 days * x hectares per day = 762 hectares

Simplifying the equation:

9x + 48 = 762

9x = 762 - 48

9x = 714

x = 714 / 9

x = 79.33 hectares per day

Therefore, the second brigade plowed approximately 79.33 hectares per day.

Comparison of the Two Brigades

To determine which brigade plowed more and by how much, we compare the average hectares plowed per day by the first brigade (6 hectares) with the hectares plowed per day by the second brigade (79.33 hectares).

The second brigade plowed significantly more hectares per day compared to the first brigade. The difference in hectares plowed per day between the two brigades is:

Difference = Hectares plowed per day by the second brigade - Average hectares plowed per day by the first brigade

Difference = 79.33 hectares - 6 hectares

Difference = 73.33 hectares

Therefore, the second brigade plowed more hectares per day than the first brigade by approximately 73.33 hectares.

Please note that the calculations are based on the given information and assumptions made.
