Question

Два трактора вспахали поле. Производительность первого трактора 12 га в день, а второго — 10 га в день. Первый трактор работал m дней, а второй трактор работал на 3 дня больше. Чему равна площадь вспаханного поля?​

Answer 1

Ответ:

Пошаговое объяснение:

12 m+ 10(m+3)=12m+10m+30=22m+30 (га)

Answer 2

Calculating the Area of the Plowed Field

To calculate the area of the plowed field, we can use the information provided about the productivity of the tractors and the number of days they worked.

Productivity of the first tractor: 12 hectares per day Productivity of the second tractor: 10 hectares per day Number of days the first tractor worked: m days Number of days the second tractor worked: m + 3 days

To find the total area plowed by both tractors, we can use the following equation: Total area = (Productivity of the first tractor * Number of days it worked) + (Productivity of the second tractor * Number of days it worked)

Substituting the given values: Total area = (12 * m) + (10 * (m + 3))

Expanding the equation: Total area = 12m + 10m + 30

Simplifying the equation: Total area = 22m + 30 hectares

So, the total area of the plowed field is 22m + 30 hectares.

This calculation assumes that the tractors worked at a constant productivity rate over the given number of days.
