Using Scale to Find the Distance Between Two Cities on a Map.

A driver is traveling at a constant speed on Interstate 90 outside of Chicago. Use the tools to determine the distance she traveled from Point A to Point B.

(1). Use the Distance tool in the applet above to measure the distance between points A and B.

(2). If she traveled from Point A to Point B in 8 minutes, did she obey the speed limit of 55 miles per hour? Explain your reasoning.

(3). A traffic helicopter flew directly from Point A to Point B in 8 minutes. Did the helicopter travel faster or slower than the driver? Explain or show your reasoning in the applet.
