Acircular test track for cars has a circumference of 3.5 km . a car travels around the track from the southernmost point to the northernmost point. what distance does the car travel?

The car would have traveled exactly one-half of the circumference of the track, since it would have gone from one extreme point to its opposite extreme point. This would be equal to (3.5 / 2), or 1.75 km. The northernmost point would be 1.75km away from the southernmost point.
