Question

2 работника выполнюят работу за 6 часов. За сколько часов выполнят работу 3 работника

Answer 1

Если 2 работника за 6 часов выполняют работу, то
1 работник выполняет работу за 2 * 6 = 12 часов.
Соответственно 3 работника за  $\frac{12}{3}$ = 4 часа

Answer 2

To solve this problem, we can use the concept of "person-hours." If 2 workers can complete the job in 6 hours, they have collectively done 2 x 6 = 12 person-hours of work. Now, we want to find out how long it will take for 3 workers to complete the same job.

Let x be the number of hours it takes for 3 workers to complete the job. Since the amount of work done is the same, we can set up a proportion:

2 workers' hours : 3 workers' hours = 12 person-hours : x person-hours

The equation would be:

2 * 6 : 3 * x = 12 : x

Now, solve for x:

12 : 3x = 12 : x

Cross-multiply:

12 * x = 3 * 12

Divide by 12:

x = 3

So, 3 workers will complete the job in 3 hours.
