If 7 inches of snow have fallen over the past 4 hours, we can first calculate the rate of snowfall per hour:
\[ \text{Rate} = \frac{7 , \text{inches}}{4 , \text{hours}} = 1.75 , \text{inches per hour} \]
Now, to find out how much snow will fall over the next 24 hours at the same rate, we multiply the hourly rate by 24 hours:
\[ \text{Total snowfall} = 1.75 , \text{inches/hour} \times 24 , \text{hours} = 42 , \text{inches} \]
So, if the pace continues, a total of 42 inches of snow will fall over the next 24 hours.
