To find how many miles Lorinda can walk in 45 minutes, you can set up a proportion based on her walking rate.
Lorinda's rate is 1.8 miles in 30 minutes. We want to find out how many miles (let's call this \( x \)) she can walk in 45 minutes.
The appropriate proportion can be set up as follows:
\[
\frac{1.8}{30} = \frac{x}{45}
\]
So, the correct answer is:
**1.8/30 = x/45**
