Problem Analysis

A cook made 28 dumplings in 7 minutes. We need to determine how long it will take for the cook to make 40 dumplings if they make one more dumpling per minute.

Solution

To solve this problem, we can set up a proportion based on the given information. Let's assume that the number of minutes it takes to make 40 dumplings is x.

We can set up the following proportion:

28 dumplings / 7 minutes = 40 dumplings / x minutes

To solve for x, we can cross-multiply and solve for x:

28 * x = 7 * 40

Simplifying the equation:

28x = 280

Dividing both sides by 28:

x = 10

Therefore, it will take the cook 10 minutes to make 40 dumplings if they make one more dumpling per minute.

Answer

The cook will be able to make 40 dumplings in 10 minutes if they make one more dumpling per minute.
