Final answer:
The legal speed limit on state highways in Kentucky is 55 mph. Speed limits are there for safety and vary by road type, and it's important to convert them to different units like meters per second or miles per hour as necessary.
Step-by-step explanation:
In Kentucky, the legal speed limit on state highways is c) 55 mph. This limit applies unless otherwise posted and is in place to ensure the safety and orderly flow of traffic. Speed limits can vary depending on the type of road and the area (urban vs. rural), so always look for signage that might indicate a different limit.
Conversion of Speed Units
To convert a speed limit from kilometers per hour to miles per hour, we use the conversion factor that 1 mile is approximately 1.609 kilometers. On the other hand, to convert kilometers per hour to meters per second, we can use the factor that 1 m/s is equal to 3.6 km/h. Figuring out speed limits in different units of measure can be a common task in both everyday life and in solving physics problems.
