Final answer:
The minimum speed on interstate highways in good weather is usually around 40 mph. When converting speeds like 100 km/h, it translates to approximately 27.778 m/s or 62 mph.
Step-by-step explanation:
The speed limit on some interstate highways is roughly 100 km/h. To understand the slowest permissible speed on an interstate, we have to consider the context provided by various state laws and the highway traffic conditions. Generally, there are also minimum speed limits to ensure that traffic flows smoothly and safely, although specific speeds can vary by state and road conditions. In good weather and traffic permitting, the minimum speed is often set at 40 mph to prevent congestion and potential hazards from much slower moving vehicles. If we were to convert 100 km/h to meters per second, we would use the conversion factor where 1 km/h is equal to 0.27778 m/s (100 km/h × 0.27778 m/s/km/h), resulting in roughly 27.778 m/s. In miles per hour, 100 km/h will roughly be 62 mph, as 1 mile is approximately 1.609 kilometers.
