Answer 1

Problem Analysis

We are given that the first typist can type 8 pages in 1 hour, and the second typist can type the same number of pages in 4 hours as the first typist can type in 3 hours. We need to find out how many pages both typists can type in 11 hours of work together.

Solution

Let's calculate the number of pages each typist can type per hour:

- The first typist can type 8 pages in 1 hour, so she can type 8 pages per hour. - The second typist can type the same number of pages in 4 hours as the first typist can type in 3 hours. This means that the second typist can type 8 pages in 4 hours, which is equivalent to 2 pages per hour.

Now, let's calculate the total number of pages both typists can type in 11 hours of work together:

- The first typist can type 8 pages per hour. So in 11 hours, she can type 8 pages/hour x 11 hours = 88 pages. - The second typist can type 2 pages per hour. So in 11 hours, she can type 2 pages/hour x 11 hours = 22 pages.

Therefore, both typists can type a total of 88 pages + 22 pages = 110 pages in 11 hours of work together.

Answer

Both typists will be able to print a total of 110 pages in 11 hours of work together.
