Part 2/6:
To solve this problem, one must follow several pivotal steps. Firstly, reading the statement carefully is crucial, ensuring that all details are understood. The key information includes the total distance (440 km) and the distance already traveled (120 km).
Next, envisioning the situation aids comprehension. The driver’s journey is visually estimated, and the problem prompts the need for subtraction to find the remaining distance. By subtracting the distance already covered from the total distance, we establish that:
[
440 \text{ km} - 120 \text{ km} = 320 \text{ km}
]
Thus, it is concluded that there are 320 kilometers left for the driver to complete their journey.
