Here's the calculation:
Time = Distance / Average Speed
Time = 161 km / 80 km/h
Time ≈ 2 hours
However, it's important to note that real-world driving conditions can vary, and your actual driving time may be longer or shorter depending on several factors, such as traffic, road conditions, weather, speed limits, and stops along the way. Therefore, it's always a good idea to add some extra time to your estimated travel time to account for any unforeseen delays or unexpected situations.
