Final answer:
The student's question involves converting a 100 km/h speed limit on an interstate highway to miles per hour. Using the conversion factor, 1.0 miles equals 1.609 kilometers. The conversion result is approximately 62.15 mph, showing that Georgia's expressway speed limit of 70 mph is higher than the typical interstate highway limit.
Step-by-step explanation:
The question asked involves a conversion of speed limits from kilometers per hour to miles per hour, which falls under mathematical operations specifically dealing with unit conversions. The speed limit on Georgia expressways is mentioned to be up to 70 mph (miles per hour). For a better understanding, let's consider a typical interstate highway speed limit which is about 100 km/h. To convert this to miles per hour, we use the conversion factor where 1.0 mile is approximately equal to 1.609 kilometers.
To find out how many miles per hour 100 km/h is, we divide 100 by 1.609, yielding roughly 62.15 mph. Therefore, this mathematical operation shows that a speed limit of 100 km/h on an interstate highway is comparable to a bit over 62 mph. A limit of 70 mph on Georgia expressways allows for a faster travel speed compared to the standard highway speed limit.
