To determine the distance between two numbers on a number line, we can use the formula:

\[ \text{Distance} = |a - b| \]

where \( a = -18.26 \) and \( b = -2.45 \).

Calculating:

\[ \text{Distance} = |-18.26 - (-2.45)| \]

This simplifies to:

\[ |-18.26 + 2.45| = |-18.26 + 2.45| = |-15.81| \]

Since distance is always a positive value, we drop the negative sign:

\[ \text{Distance} = 15.81 \]

So, the correct response is:

15.81
