To determine the rate at which the rain is falling, you would typically need to analyze the data points on the graph showing rainfall measurements over time.
- If the graph shows total rainfall (for example, inches) over a duration (hours), you would look for the difference in rainfall between two time points and then divide that difference by the time elapsed between those measurements.
For example: If the rainfall was measured at 3 inches at the start and then 1 inch after one hour, the rate would be:
\[ \text{Rate} = \frac{\text{Change in rainfall}}{\text{Time}} = \frac{3 , \text{inches} - 1 , \text{inch}}{1 , \text{hour}} = \frac{2 , \text{inches}}{1 , \text{hour}} = 2 , \text{inches per hour}. \]
If you can provide specific values from the graph or describe it further, I can help calculate the exact rate. Otherwise, the answer requires specific graph data to finalize.
