Answer 3

Problem Analysis

We have two operators who can type at different speeds. One operator can type 30 pages of text in 6 hours, while the other operator can type 6 pages less in the same amount of time. We need to determine how long it will take for both operators to type a total of 72 pages of text when working together.

Solution

Let's calculate the typing speed of the second operator. If the first operator can type 30 pages in 6 hours, then the second operator can type 30 - 6 = 24 pages in 6 hours.

Now, let's calculate the combined typing speed of both operators. The first operator can type 30 pages in 6 hours, which means their typing speed is 30 / 6 = 5 pages per hour. The second operator can type 24 pages in 6 hours, which means their typing speed is 24 / 6 = 4 pages per hour.

To find out how long it will take for both operators to type a total of 72 pages, we need to calculate the total number of hours required. Let's assume it takes x hours for them to type 72 pages together.

The first operator's typing speed is 5 pages per hour, so in x hours, they will type 5x pages. The second operator's typing speed is 4 pages per hour, so in x hours, they will type 4x pages.

The total number of pages typed by both operators in x hours is 5x + 4x = 9x.

Since we know that the total number of pages typed is 72, we can set up the equation: 9x = 72

To solve for x, we divide both sides of the equation by 9: x = 72 / 9 = 8

Therefore, it will take both operators 8 hours to type a total of 72 pages of text when working together.

Answer

Both operators will take 8 hours to type a total of 72 pages of text when working together.
