Final answer:

To convert 100 kilometers per hour to miles per hour, divide the speed in km/h by the conversion factor of 1.609, resulting in roughly 62.15 mph.

Step-by-step explanation:

Converting Kilometers per Hour to Miles per Hour

The question asks to convert the speed limit from kilometers per hour (km/h) to miles per hour (mph). Given that the speed limit on some interstate highways is roughly 100 km/h and 1.0 mile is about 1.609 kilometers, we can calculate the speed in mph using the conversion factor.

To convert kilometers to miles, we divide the speed in km/h by the conversion factor 1.609. Performing this calculation:


100 km/h ÷ 1.609 km/mile = 62.15 mph (approximately)

Therefore, 100 km/h is roughly equivalent to 62.15 mph.
