Final answer:
The maximum speed limit for Interstate highways varies but can be as high as 85 mph (137 km/h). The correct answer is option F).
Step-by-step explanation:
The maximum speed limit for Interstate highways, freeways, or urbanized areas varies by location and can be as high as 85 mph (137 km/h). However, 75 mph (120 km/h) is a common maximum speed found in many states for rural Interstate highways.
To convert speeds from km/h to m/s, you can use the conversion factor 1 m/s = 3.6 km/h. Thus, for example, a speed limit of 100 km/h is equivalent to about 27.8 m/s (100/3.6). When it comes to miles per hour, you can use the approximation that 1 km is about 0.621371 miles.
Therefore, 100 km/h is approximately equal to 62 miles per hour (100 * 0.621371). It is important to note that these speed limits can vary from state to state and may have certain restrictions.
