Question

опытный оператор за 48 часов набирает на компьютере 192 страницы, а начинающий 96 страниц За сколько часов они наберут 486 страниц, работая вместе?? ПОЖАЛУЙСТА ОЧЕНЬ НАДО!!!! прошу!!!

Answer 1

1) 192 : 48 = 4 страницы - набирает за 1 час опытный оператор.
2) 96 : 48 = 2 страницы - набирает за 1 час начинающий оператор.
3) 4 + 2 = 6 страниц - набирают за 1 час они вместе.
4) 486 : 6 = 81 час - за столько они вместе наберут 486 страниц.
Ответ: за 81 час.

Answer 2

Calculating the Time Required to Complete 486 Pages

To find out how long it will take the experienced and novice operators to complete 486 pages working together, we can use the concept of their combined work rate.

Let's denote: - The experienced operator's work rate as E (pages per hour). - The novice operator's work rate as N (pages per hour). - The total number of pages to be completed as T (486 pages).

We can use the following equation to represent the combined work rate: E + N = Total work rate

To find the time required, we can use the formula: Time = Total work / Combined work rate

Calculating the Combined Work Rate

The experienced operator completes 192 pages in 48 hours, so their work rate is: E = 192 pages / 48 hours = 4 pages per hour.

The novice operator completes 96 pages in 48 hours, so their work rate is: N = 96 pages / 48 hours = 2 pages per hour.

The combined work rate is: E + N = 4 pages per hour + 2 pages per hour = 6 pages per hour.

Calculating the Time Required

Using the formula: Time = Total work / Combined work rate we can calculate the time required for both operators to complete 486 pages working together: Time = 486 pages / 6 pages per hour = 81 hours.

So, working together, the experienced and novice operators will take 81 hours to complete 486 pages.
