Final answer:
To find the unit rate (lapse per minute), create a ratio table with the given values and determine the number of laps per minute.
Step-by-step explanation:
To find the unit rate (lapse per minute), we can create a ratio table with the given values:
Minutes Laps
0 0
2 1
4 2
6 3
In this case, the unit rate is the number of laps per minute.
As we can see from the table, for every 2 minutes, there is 1 lap, or 0.5 laps per minute.
Therefore, the unit rate is 0.5 laps per minute.
