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 вспахала больше и на сколько?

Answer 1

8 * 48 =384 га вспахала первая бригада
762 - 384= 378 га вспахала вторая бригада
378 / 9=42 га в день вспахивала вторая бригада
384 - 378 = 6 га первая бригада вспахала на 6 га больше чем вторая.

Answer 2

48*8=384 га вспахала 1 бригада за 8 дней
762-(48*8)=378  га вспахала вторая бригада
378/9=42 га вспахивала в день 2 бригада
48-42=6га на столько больше вспахивала 1 бригада в день

Answer 3

Calculation of Hectares Plowed per Day

To calculate the number of hectares plowed per day by the second brigade, we can use the information provided about the first brigade's work.

According to the information given, the first brigade worked for 8 days and plowed 48 hectares per day. Therefore, the total area plowed by the first brigade is:

8 days * 48 hectares/day = 384 hectares.

Since the two brigades together plowed 762 hectares, we can subtract the area plowed by the first brigade from the total to find the area plowed by the second brigade:

762 hectares - 384 hectares = 378 hectares.

Therefore, the second brigade plowed 378 hectares in total.

To find the number of hectares plowed per day by the second brigade, we divide the total area plowed by the number of days worked:

378 hectares / 9 days = 42 hectares/day.

So, the second brigade plowed 42 hectares per day.

Comparison of the Two Brigades

To determine which brigade plowed more and by how much, we compare the number of hectares plowed per day by each brigade.

The first brigade plowed 48 hectares per day, while the second brigade plowed 42 hectares per day. Therefore, the first brigade plowed more hectares per day.

The difference in the number of hectares plowed per day between the two brigades is:

48 hectares/day - 42 hectares/day = 6 hectares/day.

So, the first brigade plowed 6 hectares more per day than the second brigade.

In summary, the second brigade plowed 42 hectares per day, while the first brigade plowed 48 hectares per day, making the first brigade more productive by 6 hectares per day.
