Carmen ran 2 laps around the track in 6 minutes. What are the unit rates in laps per minute and minutes per lap?
To find the unit rate in laps per minute, divide the number of laps by the number of minutes: 2 laps / 6 minutes = 1/3 lap per minute.
To find the unit rate in minutes per lap, divide the number of minutes by the number of laps: 6 minutes / 2 laps = 3 minutes per lap. Answer: \boxed{\frac{1}{3}} \text{ lap per minute and } \boxed{3} \text{ minutes per lap}.
