The table of values below represents a linear function and shows the amount of snow that has fallen since a snowstorm began. What is the rate of change?Snowfall AmountLength of Snowfall(hours)Amount of Snow on the Ground(inches)03.30.54.51.05.71.56.92.08.1

The rate of change is the change in snow depth divided by the change in time. From 0 to 0.5 hours, the amount rises from 3.3 to 4.5 inches, an increase of 1.2 inches in 0.5 hours. Since 1.2 ÷ 0.5 = 2.4, the rate is 2.4 inches per hour, choice B.
