To find the distance between two numbers on a number line, we can use the formula:
\[
\text{Distance} = |a - b|
\]
where \(a\) and \(b\) are the two numbers.
In this case, let \(a = -18.26\) and \(b = -2.45\).
Calculating the distance:
\[
\text{Distance} = |-18.26 - (-2.45)| = |-18.26 + 2.45| = |-18.26 + 2.45| = |-15.81|
\]
Since distance is always a positive value, we have:
\[
\text{Distance} = 15.81
\]
Thus, the correct response is:
**B. 15.81**
