Final answer:
The typical maximum speed limit on 2-lane highways outside urban areas is 80 km/h. This translates to 22.2 meters per second and approximately 49.7 miles per hour.
Step-by-step explanation:
The maximum speed limit on 2-lane highways outside of towns, cities, villages, or built-up areas can vary from one place to another, and it is important always to follow the local posted speed limits. However, a common standard in many jurisdictions, unless otherwise posted, is 80 km/h for such highways. This is approximately 49.7 miles per hour.
To convert km/h to m/s, you can use the conversion factor that 1 km/h equals 0.27778 m/s. Therefore, 80 km/h is equivalent to 80 x 0.27778 = 22.2 m/s. As for converting km/h to mi/h, you use the conversion factor that 1 km is approximately 0.62137 miles. Therefore, 80 km/h is equivalent to 80 x 0.62137 = 49.7 mi/h. These calculations are critical when comparing speed limits in different measurement systems or when driving in different countries.
