Question

State and local agencies have the authority to set speed limits for roadways. The table below lists distances and time measurements for cars traveling the legal speeds of rural freeways in several states. Which state has the highest average speed limit on rural freeways?

Answer 1

To find which state has the highest average speed limit on rural freeways, you need to convert km/h to mi/h using the conversion factor 1 mile = 1.609 kilometers. A speed limit of 100 km/h is equivalent to approximately 62.14 mi/h.

Step-by-step explanation:

The question requires converting speed limits from kilometers per hour (km/h) to miles per hour (mi/h) in order to determine which state has the highest average speed limit on rural freeways. The conversion factor between kilometers and miles is 1 mile = 1.609 kilometers.

Given the speed limit on some interstate highways is roughly 100 km/h, we use the conversion factor to calculate this speed in miles per hour. The conversion is as follows:

1. Divide 100 km by 1.609 to convert kilometers to miles.
2. The result of this conversion is approximately 62.14 miles per hour (100 km/h = 100 / 1.609 mi/h).

Therefore, a rural speed limit of 100 km/h is equivalent to about 62.14 mi/h, and you can use this information to compare the average speed limits of rural freeways in different states.
