Final answer:
Without the current rate of snowfall, we cannot determine how many inches of snow will fall in 24 hours. We know that more than three inches have fallen, causing school closures, but no further calculations can be made.
Step-by-step explanation:
The student's question is about calculating snowfall over a period of 24 hours given a certain rate of snowfall. However, the provided information does not include the current rate of snowfall.
The additional information given:
Sunny day snow melt rate calculations.
Time required for sunlight to melt ice.
While this information is related to snowfall and melting, none of it provides a specific rate of snowfall that can be used to calculate the total amount of snow for a 24-hour period. Therefore, we cannot answer the original question with certainty without additional details regarding the rate of snowfall. We can infer that more than three inches of snow have fallen because the schools were closed, but this only confirms that the minimum amount of snowfall exceeded three inches.
