Problem Analysis

We are given that the number of wagons in front of the wagon in which Anton is traveling is equal to the number of wagons behind him. We need to determine the total number of wagons in the train if there are 7 wagons in front of Anton's wagon. Additionally, we need to find the wagon in which Anton is traveling if the train consists of 19 wagons.

Solution

Let's solve the problem step by step:

1. We are given that the number of wagons in front of Anton's wagon is 7. Let's represent this information mathematically: - Number of wagons in front of Anton's wagon = 7

2. We are also given that the number of wagons behind Anton's wagon is equal to the number of wagons in front of him. Let's represent this information mathematically: - Number of wagons behind Anton's wagon = Number of wagons in front of Anton's wagon = 7

3. To find the total number of wagons in the train, we can add the number of wagons in front of Anton's wagon, Anton's wagon itself, and the number of wagons behind Anton's wagon: - Total number of wagons in the train = Number of wagons in front of Anton's wagon + Anton's wagon + Number of wagons behind Anton's wagon - Total number of wagons in the train = 7 + 1 + 7 - Total number of wagons in the train = 15

4. Therefore, if there are 7 wagons in front of Anton's wagon, the total number of wagons in the train is 15.

5. Now, let's find the wagon in which Anton is traveling if the train consists of 19 wagons. We know that the number of wagons in front of Anton's wagon is 7. Therefore, the number of wagons behind Anton's wagon can be calculated as follows: - Number of wagons behind Anton's wagon = Total number of wagons in the train - Number of wagons in front of Anton's wagon - Anton's wagon - Number of wagons behind Anton's wagon = 19 - 7 - 1 - Number of wagons behind Anton's wagon = 11

6. Since the number of wagons behind Anton's wagon is 11, we can conclude that Anton is traveling in the 12th wagon.

Answer

If there are 7 wagons in front of the wagon in which Anton is traveling, the total number of wagons in the train is 15. Anton is traveling in the 12th wagon if the train consists of 19 wagons.
