To determine the best scale for representing the total snowfall data on the y-axis, we should first calculate the total snowfall from the snowstorm based on the given information.
-
First segment (2 hours at 1 inch per hour):
- Snowfall = 2 hours * 1 inch/hour = 2 inches
-
Second segment (1.5 hours of no snow):
- Snowfall = 0 inches (no snow)
-
Third segment (3 hours at 1.5 inches per hour):
- Snowfall = 3 hours * 1.5 inches/hour = 4.5 inches
Now, let's add the totals:
- Total snowfall = 2 inches + 0 inches + 4.5 inches = 6.5 inches
To represent this on the y-axis using a scale, we should consider a scale that allows for clear visualization of measurements up to at least 6.5 inches.
Among the given scale options (2, 3, 5, and 0.5), using a scale of 0.5 would allow for more precise measurement of snowfall increments (e.g., 0.5, 1, 1.5, 2, ..., 6.5). The other scales (2, 3, and 5) would be too large and would not provide enough detail to represent the total snowfall accurately.
Therefore, the best scale for representing the data on the y-axis would be 0.5.
