Answer 1

Task Summary:

A cook is able to make 28 dumplings in 7 minutes. The task is to determine how long it will take the cook to make 40 dumplings if they increase their speed by making 1 additional dumpling per minute.

Solution:

To solve this problem, we can set up a proportion based on the cook's rate of making dumplings. Let's denote the time it takes to make 40 dumplings as "x" minutes.

The cook's rate of making dumplings can be calculated by dividing the number of dumplings by the time taken. In this case, the cook's rate is 28 dumplings / 7 minutes = 4 dumplings per minute.

Since the cook is increasing their speed by making 1 additional dumpling per minute, their new rate will be 4 + 1 = 5 dumplings per minute.

We can set up the proportion:

28 dumplings / 7 minutes = 40 dumplings / x minutes

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

28 * x = 40 * 7

x = (40 * 7) / 28

x = 10 minutes

Therefore, it will take the cook 10 minutes to make 40 dumplings if they increase their speed by making 1 additional dumpling per minute.

Answer:

The cook will be able to make 40 dumplings in 10 minutes if they increase their speed by making 1 additional dumpling per minute.
