Final answer:
The question is about converting a given speed limit from kilometers per hour to miles per hour, using the conversion factor where 1 mile equals 1.609 kilometers. To convert 100 km/h to mph, divide by 1.609, resulting in approximately 62.14 mph. The precise speed limit near a railroad crossing should be obtained from local traffic laws.
Step-by-step explanation:
The question asks about the conversion of the speed limit from kilometers per hour to miles per hour. Specifically, it relates to the speed limit within 100 feet of a railroad crossing where the tracks are not visible for 400 feet in both directions. To solve such a question, we would typically use the conversion factor where 1 mile is approximately 1.609 kilometers. If the speed limit on some interstate highways is roughly 100 km/h, we would convert this to miles per hour by dividing by the conversion factor. For this specific example:
- 100 km/h divided by 1.609 km/mile ≈ 62.14 mph
This calculation is relevant to understanding speed limits and may provide context to the rules regarding railroad crossings. However, the exact speed limit that should be adhered to near a railroad crossing would be specified by local traffic laws and is not provided here. As a general safety guideline, driving slower near railroad crossings where visibility is restricted is advisable, but for the precise speed limit, one would need to refer to local regulations.
