Problem Analysis

We are given that Marina read a book with 80 pages in 4 days, and Tanya read the same book in 10 days. We need to determine who read more pages in one day and by how many.

Solution

To find out who read more pages in one day, we can calculate the average number of pages read per day for each person.

Let's start by calculating the average number of pages read per day by Marina. We can do this by dividing the total number of pages read by Marina (80) by the number of days it took her to read the book (4):

Average pages read per day by Marina = 80 pages / 4 days = 20 pages/day

Now, let's calculate the average number of pages read per day by Tanya. We can do this by dividing the total number of pages read by Tanya (80) by the number of days it took her to read the book (10):

Average pages read per day by Tanya = 80 pages / 10 days = 8 pages/day

Comparing the average number of pages read per day by Marina and Tanya, we can see that Marina read more pages in one day. She read 20 pages per day, while Tanya read only 8 pages per day.

Therefore, Marina read more pages in one day than Tanya, and she read 12 more pages per day.

Answer

Marina read more pages in one day than Tanya, and she read 12 more pages per day.
