Concept explainers
Use the figure to the right for exercises 67 and 68. This figure shows a comparison of common speed limits in miles per hour (mph) and kilometers per hour (km/h). These comparisons are approximated to the nearest kilometer per hour.
In most parts of the United States the speed limit within a school zone is 25 mph. If the speedometer reading on Edward’s foreign car is 30 km/h as he drives through a school zone, is he driving above or below the speed limit?
