Problem Analysis

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

Solution

To solve this problem, we can use a simple ratio and proportion calculation. We know that the first seamstress sewed 12 pillowcases in a certain amount of time, and the second seamstress sewed 2 duvet covers per hour. We can set up the following proportion:

3 pillowcases / 1 hour = 12 pillowcases / x hours

Simplifying the proportion, we have:

3 / 1 = 12 / x

Cross-multiplying, we get:

3x = 12

Dividing both sides by 3, we find:

x = 4

Therefore, the second seamstress sewed 4 hours in the same amount of time. Since she sewed 2 duvet covers per hour, she sewed a total of 8 duvet covers.

Answer

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