A park ranger uses negative numbers to indicate snow levels below normal. Before a snowstorm, the snow level was −1012 inches, indicating 1012 inches below normal. During the storm, the snow fell at a steady rate of 2.2 inches per hour.
After the storm, the park ranger determined the snow level to be −0.05 inches.
How long did the snowstorm last?
Drag and drop the choices to the boxes to form the correct answer.
To find the duration of the snowstorm, we need to determine how many inches of snow fell during the storm and then divide that number by the rate of snowfall.
First, we need to find the difference between the initial snow level and the final snow level:
Final snow level - Initial snow level = Difference
-0.05 inches - (-1012 inches) = Difference
-0.05 inches + 1012 inches = Difference
1011.95 inches = Difference
Next, we need to divide the difference by the rate of snowfall to find the duration of the snowstorm:
Difference / Rate of snowfall = Duration
1011.95 inches / 2.2 inches/hour ≈ Duration
Duration ≈ 459.98 hours
Therefore, the snowstorm lasted approximately 459.98 hours.
