Question

Помогите решить: Два трактора вспахали поле за 6 часов. Сколько нужно тракторов, чтобы вспахать такое же поле за 2 часа?

Answer 1

чтобы понять за сколько времени один трактор

6×2=12(ч)

чтобы найти сколько тракторов понадобится-надо разделить 12 на 2

12:2=6(т)

Answer 2

Problem Analysis

We are given that two tractors plowed a field in 6 hours. We need to determine how many tractors would be needed to plow the same field in 2 hours.

Solution

To solve this problem, we can use the concept of work. The work done by the tractors is directly proportional to the number of tractors and the time taken.

Let's assume that the work required to plow the field is represented by W. We can set up the following equation:

Work done by 2 tractors in 6 hours = Work done by x tractors in 2 hours

Mathematically, this can be written as:

2 * 6 = x * 2

Simplifying the equation, we get:

12 = 2x

Dividing both sides by 2, we find:

x = 6

Therefore, it would take 6 tractors to plow the same field in 2 hours.

Answer

To plow the same field in 2 hours, it would require 6 tractors.
