Answer 3

Problem Analysis

We are given the information that beavers can cut down a thick tree in 15 minutes, which is 12 minutes longer than it takes them to cut down a thin tree. We need to determine how long it will take the beavers to cut down one thin tree and one thick tree.

Solution

Let's assume it takes the beavers x minutes to cut down a thin tree. According to the given information, it takes them x + 12 minutes to cut down a thick tree.

To find the time it takes to cut down one thin tree and one thick tree, we need to add the time it takes to cut down each tree.

Therefore, the total time it takes to cut down one thin tree and one thick tree is x + (x + 12) minutes.

Simplifying the equation, we get:

2x + 12 minutes.

So, it will take the beavers 2x + 12 minutes to cut down one thin tree and one thick tree.

Answer

The beavers will take 2x + 12 minutes to cut down one thin tree and one thick tree.

Please note that we don't have enough information to determine the exact time it takes to cut down a thin tree.
