Answer:
The correct answer is C. Unless otherwise posted, the speed limit in an urban district is 30 mph.
Step-by-step explanation:
The speed limit within a city in the United States is generally 25 mph, although this will depend on whether it is a street with a sense, a street within a neighborhood or a street with two or more tracks in each direction, so in general, in the latter the speed is about 35 mph.
