To represent the data on the x-axis, you should consider the total time duration of the snowstorm. The snowstorm lasted for a total of 6.5 hours:
- First 2 hours: Snowing at 1 inch per hour.
- 1.5 hours: No snow.
- Next 3 hours: Snowing at 1.5 inches per hour.
Given this total duration, the best scale for the x-axis to represent the data would be:
- 0.5 hrs: This scale allows for a clear representation of short intervals, making it easy to show the changes in snowfall rates and the period of no snow.
So, 0.5 hrs would be the most suitable choice for representing the data on the x-axis.
