Question

Пожалуйста помогите решить задачу. один оператор набирает на компьютере 240 стр текста за 6 дней, а другой за 8. За сколько дней они наберут 280 страниц текста, работая вместе с такой же продуктивностью? спасибо

Answer 1

1)30-6=24ст-набирает другой оператор
2)30:6=5ст-набирает один оператор за 1 час
3)24:6=4ст -набирает другой оператор за 1 час
4)5+4=9ст -набирают два оператора за 1 час
5)72:9=8 ч-набирут

Answer 2

За день первый оператор набирает 40 строк а второй 30
280 строк они на берут вместе за 4 дня

Answer 3

Problem Analysis

We are given that one operator can type 240 pages of text in 6 days, and another operator can type the same amount of text in 8 days. We need to determine how many days it will take for them to type 280 pages of text if they work together at the same productivity level.

Solution

To solve this problem, we can calculate the individual rates of each operator and then combine their rates to find the total rate at which they can type. Finally, we can use the total rate to calculate the number of days required to type 280 pages of text.

Let's denote the rate at which the first operator types as R1 (pages per day) and the rate at which the second operator types as R2 (pages per day). We can calculate these rates using the given information.

From the problem statement, we know that the first operator can type 240 pages in 6 days, so their rate is:

R1 = 240 pages / 6 days = 40 pages per day.

Similarly, the second operator can type 240 pages in 8 days, so their rate is:

R2 = 240 pages / 8 days = 30 pages per day.

To find the combined rate of both operators, we can add their individual rates:

Total rate = R1 + R2 = 40 pages per day + 30 pages per day = 70 pages per day.

Now that we have the total rate at which they can type, we can calculate the number of days required to type 280 pages of text by dividing the total number of pages by the total rate:

Number of days = Total pages / Total rate = 280 pages / 70 pages per day = 4 days.

Therefore, it will take them 4 days to type 280 pages of text if they work together at the same productivity level.
