To determine how many total inches of snow will fall over the next 24 hours at the same pace, we can first find the rate of snowfall per hour.
In the past 4 hours, 7 inches of snow has fallen, so the snowfall rate is:
\[ \text{Rate} = \frac{\text{Total Snowfall}}{\text{Time}} = \frac{7 \text{ inches}}{4 \text{ hours}} = 1.75 \text{ inches per hour} \]
Next, we can calculate the total snowfall expected over the next 24 hours:
\[ \text{Total Snowfall} = \text{Rate} \times \text{Time} = 1.75 \text{ inches/hour} \times 24 \text{ hours} = 42 \text{ inches} \]
Therefore, if the snowfall continues at the same pace, a total of 42 inches will fall over the next 24 hours.
