Question

At 4 P.M., the total snowfall is 4 centimeters. At 7 P.M., the total snow fall is 11 centimeters. What is the mean hourly snowfall? Write you answer in simplest form as a fraction or decimal

Answer 1

Mean hourly snowfall =
`(7)/(3)` cm/hr

Explanation:

At 4 P.M., the total snowfall is 4 centimeters

Snowfall at 4 P.M = 4 cm

At 7 P.M., the total snow fall is 11 centimeters.

Snowfall at 7 P.M = 11 cm

Duration = 7 - 4 = 3 hours

Snowfall = 11 - 4 = 7 cm

`\texttt{Mean hourly snowfall = }\frac{\texttt{Snowfall}}{\texttt{Duration}}=(7)/(3)cm/hr`

Mean hourly snowfall =
`(7)/(3)` cm/hr
