Problem Analysis

We have two seamstresses who worked for the same amount of time. The first seamstress sewed 12 pillowcases at a rate of 3 pillowcases per hour. We need to determine how many duvet covers the second seamstress sewed in the same amount of time, given that she sewed 2 duvet covers per hour.

Solution

To find the number of duvet covers the second seamstress sewed, we need to calculate the total number of hours worked by both seamstresses and then multiply that by the rate of sewing for the second seamstress.

Let's calculate the number of hours worked by the first seamstress: - The first seamstress sewed 12 pillowcases at a rate of 3 pillowcases per hour. - Therefore, she worked for 12 pillowcases / 3 pillowcases per hour = 4 hours.

Now let's calculate the number of duvet covers sewed by the second seamstress: - The second seamstress sewed 2 duvet covers per hour. - Since both seamstresses worked for the same amount of time, the second seamstress also worked for 4 hours. - Therefore, the second seamstress sewed 4 hours * 2 duvet covers per hour = 8 duvet covers.

So, the second seamstress sewed 8 duvet covers in the same amount of time.

Answer

The second seamstress sewed 8 duvet covers in the same amount of time.
