Question

Переписчик в течение 4 дней может переписать 40 листов работая по 9 часов в день Во сколько дней он перепишет 60 листов работая по 12 часов в день

Answer 1

По моему получится 10

Answer 2

40/4=10 листов за 9 часов
9часов=540 минут
540/10=54 минуты на 1 лист
54*60=3240 минут
12часов=720 минут
3240/720=4 ост.360 минут
получается он перепишет за 5 дней

Answer 3

Calculating the Time Required to Rewrite Pages

To calculate the time required to rewrite 60 pages working 12 hours a day, we can use the given information that a transcriber can rewrite 40 pages in 4 days working 9 hours a day.

Let's calculate the time required.

Given: - 40 pages in 4 days working 9 hours a day - Need to find the time required to rewrite 60 pages working 12 hours a day

Using the given information, we can calculate the time required to rewrite 60 pages.

First, let's calculate the transcriber's rate per page: - Rate per page: 40 pages in 4 days working 9 hours a day - Rate per page = Total pages / (Total days * Hours per day) - Rate per page = 40 / (4 * 9) = 40 / 36 = 1.1111 pages per hour

Now, we can use the rate per page to calculate the time required to rewrite 60 pages working 12 hours a day: - Time required: 60 pages working 12 hours a day - Time required = Total pages / Rate per page - Time required = 60 / 1.1111 = 54 hours (rounded to the nearest whole number)

Therefore, the transcriber will rewrite 60 pages working 12 hours a day in approximately 54 hours.

Conclusion

Working 12 hours a day, the transcriber will rewrite 60 pages in approximately 54 hours.
