Answer 1

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

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

where \( a \) and \( b \) are the two numbers you're comparing.

In this case, let's use \( a = 6.5 \) and \( b = -7.2 \):

\[
\text{Distance} = |6.5 - (-7.2)|
\]

This simplifies to:

\[
\text{Distance} = |6.5 + 7.2| = |13.7| = 13.7
\]

Thus, the distance between 6.5 and −7.2 on a number line is **13.7**.
