Justin starts going to a new fitness. His smart watch tracks a total for 72 active minutes in the week. If he attended the class 3 times, what is the unit rate of active minutes per class?

Question

25 minutes

22 minutes

27 minutes

24 minutes

Answer 1

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

Justin has a total of 72 active minutes for 3 classes:

$$\text{Active minutes per class}=\frac{\text{Total active minutes}}{\text{Number of classes}}=\frac{72\text{ minutes}}{3\text{ classes}}=24\text{ minutes per class}$$

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