To find out how many sit-ups Lynne can do in 2 minutes, we need to determine the rate at which she is doing sit-ups.
From the given data, we can see that the number of sit-ups is increasing by 12 every 2 minutes.
Therefore, we can calculate the number of sit-ups Lynne can do in 2 minutes using the ratio:
$$\text{Sit-ups in 2 minutes} = \frac{\text{Sit-ups in 4 minutes}}{4} \times 2$$
$$\text{Sit-ups in 2 minutes} = \frac{24}{4} \times 2$$
$$\text{Sit-ups in 2 minutes} = 6 \times 2$$
$$\text{Sit-ups in 2 minutes} = 12$$
Therefore, Lynne can do 12 sit-ups in 2 minutes.
