At 5 p.m., the total snowfall is 2 centimeters. at 10 p.m., the total snowfall is 10 centimeters. what is the mean hourly snowfa
TEA [102]

Answer:

The mean hourly snowfall is 2.5 centimeters

Step-by-step explanation:

The mean hourly snowfall is the number of centimeters that fell during the period divided by the number of hours.

From 5 P.M. to 9 P.M., there are 4 hours

At 5 P.M., the total snowfall is 2 centimeters.

At 9 P.M., the total snowfall is 12 centimeters.

So in those four hours, the depth of snow increases 12-2 = 10 centimeters

10/4 = 2.5

The mean hourly snowfall is 2.5 centimeters
