This question is asking about Ilana's average speed, in laps per minute, based on the information that she ran 2 laps in 8 minutes.

To calculate average speed, you can use the formula:

$\text{Average speed} = \frac{\text{Total distance}}{\text{Total time}}$

In this case, the total distance is 2 laps, and the total time is 8 minutes. So:

$\text{Average speed} = \frac{2 \text{ laps}}{8 \text{ minutes}} = \frac{1}{4} \text{ laps per minute}$

Thus, the correct answer is:

$\boxed{\frac{1}{4} \text{ of a lap per minute}}$

Would you like further details on how to calculate speed or any other help? Here are some related questions that might interest you:

1. How would you calculate the average speed if she ran 3 laps in 10 minutes?
2. What are the differences between average speed and instantaneous speed?
3. How do you calculate speed in different units, like kilometers per hour?
4. How would you calculate the time if you know the speed and distance?
5. What other factors can affect the measurement of speed?

Tip: Always ensure the units are consistent when calculating speed!
