Q. Increases in snow levels are recorded with positive numbers. Decreases in snow levels are recorded with negative numbers.

\newline

After a winter storm, the snow on Cherry Street started melting at a rate of

\frac{1}{3} \mathrm{~cm}

per hour.

\newline

What was the total change in depth of the snow on Cherry Street after

3

hours?

\newline

_____cm

Calculate total change after $1$ hour: Calculate the total change in depth after $1$ hour: $1$ hour $\times \left(\frac{1}{3}\,\text{cm/hour}\right) = \frac{1}{3}\,\text{cm}.$
Calculate total change after $3$ hours: Calculate the total change in depth after $3$ hours: $3$ hours $\times \left(\frac{\(1\)}{\(3\)} \text{ cm/hour}\right) = \frac{\(3\)}{\(3\)} \text{ cm} = \(1\) \text{ cm}.
