Question

3 тракториста могут вспахать поле за 18 часов. Сколько потребуется трактористов, чтобы вспахать поле за 9 часов?

Answer 1

Общий объем работы (А) = Количество трактористов (сначала 3, потом X) * Скорость работы одного тракториста (N) * Время работы (сначала 18, потом 9)
A= 3 * N * 18 = X * N  * 9
3*18=Х*9
X =6 трактористов

Answer 2

18*3=54 часа это один тракторист все поле
54 : 9=6 трактористов за 9 часов

Answer 3

Calculating the Number of Tractor Drivers Needed

To calculate the number of tractor drivers needed to plow a field in 9 hours, given that 3 tractor drivers can plow it in 18 hours, we can use the concept of work done.

According to the search results, the formula for calculating the number of workers needed to complete a task in a different time is:

Number of workers = (Old time * Old workers) / New time

Using this formula, we can calculate the number of tractor drivers needed.

Given: - Old time = 18 hours - Old workers = 3 tractor drivers - New time = 9 hours

Calculation

Number of workers = (18 * 3) / 9 Number of workers = 54 / 9 Number of workers = 6

Therefore, 6 tractor drivers would be needed to plow the field in 9 hours.
