Thickness of snow at 3 p.m. $=\left[2 \frac{1}{4}+\left(3 \times 1 \frac{1}{4}\right)\right]$ inches $$\begin{aligned} & =\left(\frac{9}{4}+3 \times \frac{5}{4}\right) \text { inches } \\ & =\left(\frac{9}{4}+\frac{15}{4}\right) \text { inches } \\ & =\left(\frac{24}{4}\right) \text { inches }=6 \text { inches } . \end{aligned}$$
