Final answer:
The speed limit for business, school, and residential areas is typically 25 miles per hour (mph) or 40 kilometers per hour (km/h) to ensure pedestrian safety.
Step-by-step explanation:
In most areas, the speed limit for business, school, and residential areas is typically 25 miles per hour (mph) or 40 kilometers per hour (km/h). This speed limit is intended to ensure the safety of pedestrians, especially in areas with high foot traffic or where there are schools nearby.
For example, in the United States, residential areas often have a default speed limit of 25 mph. This is because these areas typically have a higher density of pedestrians, including children and families, and lower speed limits help reduce the risk of accidents and injuries.
It's important to note that speed limits may vary depending on local regulations and signs, so it's always recommended to obey posted speed limits and drive at safe speeds in these areas.
