Final answer:
The equation to determine the amount of snow on the ground at any given hour is s = 6 + 1.6h. It will take 3.75 hours for there to be 12 inches of snow on the ground.
Step-by-step explanation:
To determine how much snow (s) is on the ground at any given hour (h) since the storm started, we can use the equation:
s = 6 + 1.6h
This equation takes into account that there was already 6 inches of snow on the ground when the storm started, and the snow is accumulating at a rate of 1.6 inches per hour. To find out how long it will take for there to be 12 inches of snow on the ground, we can substitute s with 12 in the equation and solve for h:
12 = 6 + 1.6h
1.6h = 6
h = 6 / 1.6
h = 3.75 hours
