On a road of length $A B = 8 \text{ km}$, buses travel in both directions at a speed of $12 \text{ km/h}$. The first bus from each location starts at 6 o'clock, with subsequent buses departing every 10 minutes.

A pedestrian starts walking from $A$ to $B$ at $\frac{81}{4}$ hours; their speed is $4 \text{ km/h}$.

Determine graphically how many oncoming buses the pedestrian will meet, and also when and where these encounters will happen.
