Question

Первый тракторист может вспохать поле за 6 дней а вместе со 2-ым трактористом за 4 дня.За сколько дней закончит работу 2-ой тракторист работая один,если площадь поля 600га? Помогитее срочноооо

Answer 1

Ответ:

за 12 д. 2 тракторист

Пошаговое объяснение:

сначала надо ,6 д. (работа 1 тракт.) разделить(:) на 600= 100 г. первый тракт. в день

вот запись:

1 тракт. - 600 г. за ,6 д.

все тракт.-за 4 д.

2 тракт.-? д.

площадь поля- 600 г.

1)600:6 = 100 г за один д. 1 т.

2) дальше незнаю помог чем мог

Answer 2

Problem Analysis

We are given that the first tractor driver can plow a field in 6 days, and together with the second tractor driver, they can plow the same field in 4 days. We need to determine how many days it will take for the second tractor driver to finish plowing the field alone, given that the field has an area of 600 hectares.

Solution

Let's assume that the work rate of the first tractor driver is represented by x hectares per day. Therefore, the work rate of the second tractor driver will be (2x) hectares per day.

From the given information, we can set up the following equation based on the work rates and the time it takes to complete the job:

6x = 4(2x)

Simplifying the equation, we have:

6x = 8x

Subtracting 6x from both sides, we get:

2x = 0

This implies that the work rate of the second tractor driver is zero, which means the second tractor driver does not contribute to the work. Therefore, the second tractor driver will not be able to finish plowing the field alone.

Since the second tractor driver cannot complete the job alone, we cannot determine how many days it will take for them to finish plowing the field.

Conclusion

Based on the given information, it is not possible to determine how many days it will take for the second tractor driver to finish plowing the field alone.
