Explanation:

To determine the sun exposure time for sufficient vitamin D synthesis with SPF 15 or 30, we refer to health and medical knowledge. Generally, 10 to 20 minutes of sun exposure (even with moderate SPF like 15 - 30) is sufficient for the skin to synthesize enough vitamin D, considering factors like skin type, time of day, and latitude, but the typical range for this context is 10 to 20 minutes.
