1. The problem is to determine if the distance is 500 km. 2. To verify this, we need the context or formula used to calculate the distance. 3. If the distance was calculated using speed and time, the formula is $\text{distance} = \text{speed} \times \text{time}$. 4. Without additional information, we cannot confirm if the distance is exactly 500 km. 5. Please provide the speed and time or the original problem statement to verify the distance.
