Question

Корректор прочитывает 64 страницы в день. В рукописи 960 страниц. За сколько дней прочтёт корректор рукопись? Сколько времени в день должен читать корректор, если 1 страницу он прочитывает за 5 минут? На самом деле, прочитав 320 страниц, корректор стал читать на 16 страниц в день больше. За сколько дней прочитал корректор эту рукопись?

Answer 1

960/64=15 дней будет читать корректор.
64*5=320 минут= 5 часов 20 минут в день должен читать

320/64=5 дней читал первые 320 страниц
осталось прочитать 960-320=640 страниц
скорость увеличилась на 16 страниц 64+16=80 страниц в день
640/80=8 дней
5+8=13 дней

Answer 2

Calculation of the Number of Days to Read the Manuscript

To calculate the number of days it will take for the proofreader to read the manuscript, we can divide the total number of pages in the manuscript by the number of pages the proofreader can read in a day.

Given: - The proofreader can read 64 pages in a day. - The manuscript has 960 pages.

To calculate the number of days it will take to read the manuscript, we divide the total number of pages by the number of pages read per day:

Number of days = Total number of pages / Number of pages read per day

Number of days = 960 pages / 64 pages per day

Number of days = 15 days

Therefore, it will take the proofreader 15 days to read the entire manuscript.

Calculation of the Time Required to Read One Page

To calculate the time required to read one page, we can divide the time taken to read a certain number of pages by the number of pages read in that time.

Given: - The proofreader can read 1 page in 5 minutes.

To calculate the time required to read one page, we divide the time taken to read a certain number of pages by the number of pages read in that time:

Time required to read one page = Time taken to read a certain number of pages / Number of pages read in that time

Time required to read one page = 5 minutes / 1 page

Time required to read one page = 5 minutes

Therefore, the proofreader takes 5 minutes to read one page.

Calculation of the Number of Days to Read the Additional Pages

To calculate the number of days it took the proofreader to read the additional pages, we can divide the total number of additional pages by the number of additional pages read per day.

Given: - The proofreader started reading an additional 320 pages. - The proofreader increased their daily reading by 16 pages.

To calculate the number of days it took to read the additional pages, we divide the total number of additional pages by the number of additional pages read per day:

Number of days = Total number of additional pages / Number of additional pages read per day

Number of days = 320 pages / 16 pages per day

Number of days = 20 days

Therefore, it took the proofreader 20 days to read the additional 320 pages.
