Deseamos calcular el peso total de 5 vagones, sabiendo que:

- El primer vagón pesa 1,215 kg.
- El segundo vagón pesa 340 kg menos que el primero.
- El tercer vagón pesa 240 kg más que el segundo.
- El cuarto vagón pesa igual que el tercero.
- El quinto vagón pesa 5,985 kg.

¿Cuál es el peso total de los 5 vagones?

A) 6,075 kg
B) 6,130 kg
C) 6,550 kg

Answer :

To solve the question about the total weight of the wagons, let's go through each wagon and determine their individual weights:

1. First Wagon:
The weight of the first wagon is given as 1215 kg.

2. Second Wagon:
The second wagon weighs 340 kg less than the first wagon.
So, the weight of the second wagon is:
[tex]\( 1215 \, \text{kg} - 340 \, \text{kg} = 875 \, \text{kg} \)[/tex].

3. Third Wagon:
The third wagon weighs 240 kg more than the second wagon.
So, the weight of the third wagon is:
[tex]\( 875 \, \text{kg} + 240 \, \text{kg} = 1115 \, \text{kg} \)[/tex].

4. Fourth Wagon:
The weight of the fourth wagon is the same as the first wagon, which is 1215 kg.

5. Fifth Wagon:
The fifth wagon's weight is given as 985 kg.

Now, to find the total weight of all five wagons, we add up their individual weights:
[tex]\[
\text{Total weight} = 1215 \, \text{kg} + 875 \, \text{kg} + 1115 \, \text{kg} + 1215 \, \text{kg} + 985 \, \text{kg}
\][/tex]

Adding these together:
[tex]\( 1215 + 875 + 1115 + 1215 + 985 = 5405 \, \text{kg} \)[/tex].

Therefore, the total weight of the five wagons is 5405 kg.
