Problem Analysis

We have twenty travelers who are embarking on a journey using three boats. Two of the boats can accommodate the same number of people, while the third boat can accommodate one less person. We need to determine how many people are in each boat.

Solution

Let's assume that the number of people in each of the two boats that can accommodate the same number of people is x. The number of people in the third boat, which can accommodate one less person, will be x - 1.

To find the value of x, we can set up an equation based on the given information:

2x + (x - 1) = 20

Simplifying the equation, we get:

3x - 1 = 20

Adding 1 to both sides of the equation, we get:

3x = 21

Dividing both sides of the equation by 3, we find:

x = 7

Therefore, there are 7 people in each of the two boats that can accommodate the same number of people, and there are 6 people in the third boat.

Answer

There are 7 people in each of the two boats, and there are 6 people in the third boat.
