3. (10 points) The expressway from Lishan Town to the provincial capital is 189 kilometers long, passing through the county town. The distance from Lishan Town to the county town is 54 kilometers. At 8:30 AM, a bus departs from Lishan Town to the county town, arriving at 9:15. After a 15-minute stop, it continues to the provincial capital, arriving at 11:00. Another bus departs from the provincial capital straight to Lishan Town at 8:50 AM on the same day, traveling at 60 kilometers per hour. The time when the two buses meet is . $\qquad$
【Analysis】This problem should first find the speed and time used by car A when traveling from the county to the provincial capital. The speed is $(189 - 54) \div 1.5 = 90$ (km/h), and the time used is $(189 - 54 - 60 \times 40 \div 60) \div (90 + 60)$. Then, find the time when the two cars meet to solve the problem.

【Solution】Solution: The speed of car A when traveling from the county to the provincial capital is:
$$
\begin{aligned}
& (189 - 54) \div 1.5, \\
= & 135 \div 1.5, \\
= & 90 \text{ (km/h); }
\end{aligned}
$$

The time used by car A when traveling from the county to the provincial capital:
$$
\begin{aligned}
& (189 - 54 - 60 \times 40 \div 60) \div (90 + 60), \\
= & 95 \div 150, \\
= & \frac{19}{30} \text{ (hours), } \\
= & 38 \text{ (minutes); }
\end{aligned}
$$

The time when the two cars meet:
$$
15 + 15 = 30 \text{ (minutes), }
$$
9:30 + 38 minutes = 10:08.
Answer: The two cars meet at 10:08.
The answer is: $10:08$.
