A model of a ship is made to a scale 1 : 300.
The length of the model of the ship is 2 m. Calculate the length of the ship. 

Answer

To solve the problem, we need to use the scale factor provided. The scale of the model is given as 1:300, which means that 1 unit of measurement on the model corresponds to 300 units on the actual ship.

### Step-by-Step Solution:

1. **Understand the Scale**: The scale 1:300 means that for every 1 meter on the model, the actual ship is 300 meters long.

2. **Identify the Length of the Model**: The length of the model of the ship is given as 2 meters.

3. **Set Up the Equation**: We can express the relationship between the model and the actual ship using the scale factor:
\[ \text{Length of the model} = \frac{1}{300} \times \text{Length of the ship} \]
Substituting the known value:
\[ 2 = \frac{1}{300} \times \text{Length of the ship} \]

4. **Solve for the Length of the Ship**: To find the length of the ship, we can rearrange the equation:
\[ \text{Length of the ship} = 2 \times 300 \]

5. **Calculate the Length**:
\[ \text{Length of the ship} = 600 \text{ meters} \]

### Final Answer:
The length of the actual ship is **600 meters**.
