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.
The speed limit posted on a road in France is 89 km/h. Sam Johnson drives an American car with a speedo-meter that only displays speed in miles per hour. If Sam’s speedometer reads 65 mph, is he driving above or below the posted speed limit?
