8. (10 points) One day, Xiao Zhang set out from Town A to Town B. At the same time, Xiao Wang set out from Town B to Town A, and the two met in Village C 12 minutes after they started. The next day, Xiao Zhang and Xiao Wang set out again from Town B and Town A respectively, and returned to Town A and Town B at their original speeds. They met 6 minutes before Xiao Zhang arrived at Village C, so how many more \qquad minutes will it take for Xiao Wang to reach Town B.
【Solution】Solution: The time Xiao Wang takes to complete the entire journey:
$$
12+6+12=30 \text { (minutes) }
$$

The ratio of the distances traveled by Xiao Zhang and Xiao Wang when they meet on the first day is:
$$
\begin{array}{l}
12:(6+12) \\
=12: 18 \\
=2: 3
\end{array}
$$

Therefore, the speed ratio of Xiao Zhang to Xiao Wang is 3:2, and the time ratio for them to complete the entire journey is $2: 3$
$$
\begin{array}{l}
30 \times \frac{2}{3}=20 \text { (minutes) } \\
20-12-6=2 \text { (minutes) }
\end{array}
$$

Answer: In another 2 minutes, Xiao Wang will arrive at Town B.
The answer is: 2 .
