Question

Minnesota speed limits are:

__ mph in alleys
__ mph in urban areas
__ mph in all other locations not listed
In school zones, ________ speed when children are present.

Answer 1

The question is about the enforcement of speed limits and provides related physics problems for converting speed between kilometers per hour and other units like meters per second and miles per hour.

Step-by-step explanation:

The student is inquiring about speed limits in various locations in Minnesota and wants to know the speed you should drive in school zones when children are present. However, the information provided relates to understanding and converting speed units, specifically from kilometers per hour (km/h) to meters per second (m/s) and miles per hour (mi/h).

For example, when we are given that the speed limit on some interstate highways is roughly 100 km/h, we can convert this to meters per second by using the conversion factor 1 km/h = 0.277 m/s. Therefore, 100 km/h would convert to approximately 27.7 m/s. To convert kilometers per hour to miles per hour, we can use the conversion factor 1 km = 0.621371 miles. Thus, 100 km/h is equivalent to about 62.1 mi/h.

Answer 2

- The speed limit in alleys is typically 10 mph.
- In urban areas, the speed limit is usually around 30 mph.
- In all other locations not specifically listed, the speed limit is typically 55 mph.

As for school zones, the speed limit is typically reduced to a maximum of 20 mph when children are present.
