Justin starts going to a new fitness class his smart watch tracks a total of 72 active minutes in the week if he attended the class 3 times what is the unit rate of active minutes per classs

To find the unit rate of active minutes per class, divide the total active minutes (72) by the number of times Justin attended the fitness class (3).

The unit rate of active minutes per class is therefore 72/3 = <<72/3=24>>24 minutes per class. Answer: \boxed{24}.

To find the unit rate of active minutes per class, we divide the total number of active minutes by the number of classes attended.

The total number of active minutes over the week is 72.

Justin attended the class 3 times.

To find the unit rate, we divide the total number of active minutes (72) by the number of classes (3):

Unit rate = total active minutes / number of classes
= 72 minutes / 3 classes
= 24 minutes per class

Therefore, the unit rate of active minutes per class is 24 minutes.
