Final answer:
To find the unit rate of a woman running 40 laps in 20 minutes, divide the total laps by the total time, resulting in 2 laps per minute.
Step-by-step explanation:
The question asks about finding the unit rate of a woman running 40 laps around a track in 20 minutes. To calculate the unit rate, we divide the total number of laps by the total time in minutes. This will give us the number of laps per minute.
The unit rate calculation is as follows:
Start by setting up the fraction with laps on the top (numerator) and minutes on the bottom (denominator): 40 laps / 20 minutes.
Divide 40 by 20 to find the number of laps per minute: 2 laps per minute.
Therefore, the woman's unit rate is 2 laps per minute.
