Final answer:
In 6 hours, 4.5 inches of snow fell at a rate of 3/4 inches per hour, exceeding the three-inch benchmark that mandates school closures.
Step-by-step explanation:
To calculate the total amount of snow that fell in 6 hours at a rate of 3/4 of an inch per hour, you would multiply the rate of snowfall by the number of hours:
- Rate of snowfall = 3/4 inches per hour
- Number of hours = 6 hours
- Total snowfall = Rate of snowfall × Number of hours = (3/4) × 6
Performing the multiplication, 3/4 × 6 equals 18/4, which simplifies to 4 and 1/2 inches of snow. This calculation tells us that the total amount of snow that fell over the six-hour period was 4.5 inches. Given the information that if it snows more than three inches, schools are mandated to close, and knowing that the schools closed, we can confirm that it indeed snowed more than three inches.
