Final answer:
The speed limit on county or township highways outside of towns can vary, but it's typically higher than in towns or residential areas. For interstate highways, speeds can be around 62 mph (100 km/h). Conversion between kilometers and miles is necessary to understand and adhere to speed limits when provided in different units.
Step-by-step explanation:
The speed limit on county or township highways outside of towns varies depending on the jurisdiction and the specific road conditions. In some areas, like interstate highways, the speed limits can be as high as 100 km/h, which is approximately 62 miles per hour. However, for roadways that are not part of the interstate network, speed limits might be lower to accommodate local safety and road conditions. Given the examples, the speed limits on highways outside of towns are often higher than in residential areas, where a typical limit would be around 30 miles per hour or 50 kilometers per hour. The historical context also shows that as roads improved over time, speed limits likely evolved to reflect these changes. In the case of the township highway matrix provided, the values suggest potential speed limits (e.g., 36, 35, 30, etc.), yet without a clear context, one can't definitively state the speed limit for a township highway outside of towns. To convert the speed from kilometers per hour to miles per hour, you can use the conversion factor where 1 mile is approximately 1.609 kilometers, or conversely, 1 kilometer is roughly 0.621 miles.
