Final answer:
Speed limits on highways are often around 60 miles per hour, which equates to roughly 100 km/h. Converting 80 km/h to miles per hour results in approximately 49.7 mi/h.
Step-by-step explanation:
On a non-divided state highway, vehicles may not exceed certain speed limits which could be dependent on the state or country's traffic laws. In some cases, interstate highways may have speed limits of approximately 100 km/h. To convert this to miles per hour, we use the conversion factor where 1.0 mile is about 1.609 kilometers. The calculation is as follows:
- 100 km/h divided by 1.609 km/mi equals approximately 62.15 mi/h. Therefore, on some highways, the limit is often around 60 miles per hour (rounded down to the nearest whole number for traffic signs).
For another example, a speed limit of 80 km/h is equivalent to about:
- 80 km/h divided by 3.6 to convert it into meters per second, which equals approximately 22.2 m/s.
- 80 km/h divided by 1.609 km/mi, which gives approximately 49.7 mi/h.
Remember, while driving, it's important to adhere to the posted speed limits to ensure safety and avoid traffic violations.
