To compare the in-town speed limit to the highway speed limit, you would state it in terms of "greater than", "less than", or "equal to" based on the numerical values presented on the number line.
For example, if the in-town speed limit is 25 miles per hour and the highway speed limit is 55 miles per hour, you could say:
"The in-town speed limit is less than the highway speed limit."
In mathematical terms, this can be expressed as: \( 25 \text{ mph} < 55 \text{ mph} \)
