The mean hourly snowfall is 1.167 centimeters.

### What is the mean?

The mean is the average value of a data set.
The mean is calculated by dividing the total amount by the number of items in the data set.

### Data and Calculations:

Total snowfall at 5 p.m. = 5 centimeters
Total snowfall at 11 p.m. = 12 centimeters
Change in total snowfall at 11 p.m. = 7 centimeters (12 – 5)
Change in total time between 5 p.m and 11 p.m. = 6 hours (11 p.m. – 5 p.m.)
Mean hourly snowfall = 1.167 centimeters (7 cm /6 hrs)
Thus, the mean hourly snowfall is 1.167 centimeters.
