Question

Команда из 8 рабочих выполняет роботу за 5 дней, работая по 6 часов в день. за сколько дней закончат работу 10 рабочих, работая по 8 часов в день?

Answer 1

Попробую. Но не уверена)
каждый рабочий получается работал 5*6 часов = 30 часов.
8 рабочих в итоге все вместе отработали 8*30 = 240 часов (как бы человеко-часов)
Значит для той работы нужно 240 человеко-часов.
пусть х дней -надо 10 человекам по 8 часов в день для этой же работы. Т.е в человеко-часах это будет 10*8х
Уравнение:
10*8х=240
80х=240
х=3 (дня) - нужно 10 человекам чтобы сделать ту же работу, работая по 8 часов.
Ответ: 3 дня. 

Answer 2

Calculating the Work Completion Time

To calculate the time it takes for 10 workers to complete a task, we can use the concept of "man-days." The number of man-days required to complete a task is the product of the number of workers, the number of days, and the number of hours worked per day. We can use this concept to find the time required for 10 workers to complete the task.

Given: - 8 workers complete the task in 5 days, working 6 hours per day. - We need to find out how many days it will take for 10 workers to complete the same task, working 8 hours per day.

Solution

First, let's calculate the total man-days required for 8 workers to complete the task: Total man-days for 8 workers = 8 workers * 5 days = 40 man-days

Now, we can use the total man-days to find the time required for 10 workers to complete the task: Total man-days for 10 workers = 10 workers * x days * 8 hours per day, where x is the number of days.

We can set up a proportion to solve for x: 8 workers * 5 days * 6 hours per day = 10 workers * x days * 8 hours per day

Solving for x: 8 * 5 * 6 = 10 * x * 8 240 = 80x x = 240 / 80 x = 3

Answer

Therefore, it will take 10 workers 3 days to complete the task, working 8 hours per day.
