She can word process 36 pages.

#### Work Step by Step

First, we translate the question into an equation: $\frac{30}{4} = \frac{270}{x}$ (270 minutes = 4.5 hours) Now, we solve for $x$ by cross multiplying, which states that if $\frac{a}{b} = \frac{c}{d}$, then $ad = bc$. This result can be achieved by multiplying both sides by $cd$. $30x = 1080 \rightarrow x = 36$
