Final answer:
In a school zone, the speed limit is typically set below the posted speed limit outside the school zone. This reduced speed limit is in effect for a certain number of minutes before and after school opens and closes to accommodate increased pedestrian traffic. Following the posted speed limit helps ensure the safety of everyone in the school zone.
Step-by-step explanation:
In a school zone, the speed limit is usually reduced to ensure the safety of students. The speed limit is typically set at a certain number of miles per hour (mph) below the posted speed limit outside the school zone. The exact value can vary depending on local regulations. For example, if the posted speed limit outside the school zone is 30 mph, the speed limit in the school zone might be set at 20 mph.
The question also mentions a specific time frame, which is ______ minutes before and after school opens and closes. This indicates that the reduced speed limit is in effect during this time period to account for increased pedestrian traffic during arrival and dismissal times. The actual number of minutes can vary depending on the specific school and local regulations.
It's important to follow the posted speed limit in school zones to ensure the safety of everyone in the area. By driving at a slower speed, there is more time to react to any unexpected situations and reduce the risk of accidents.
