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 class? (1 point)
To find the unit rate of active minutes per class, divide the total number of active minutes by the number of classes:
72 active minutes / 3 classes = <<72/3=24>>24 active minutes per class.
So, the unit rate of active minutes per class is 24. Answer: \boxed{24}.
