Step-by-step explanation:
The question asks about the speed limit in a city, which is related to traffic regulations. The speed limit is the maximum speed allowed by law on a particular road or area. In most cities, unless otherwise posted, the speed limit is typically around 30-40 miles per hour.
For example, in the town of Jacinto City, Texas, the speed limit is 30 miles per hour. However, it's important to note that there is some leeway in enforcing speed limits due to the potential inaccuracies of speedometers.
Overall, the speed limit inside a city can vary, but it is usually indicated by signs and should be followed for safety reasons.
