Using the provided map, answer the following questions: 1.1 Identify the primary national road used when travelling from Morningside to Beacon Bay. 1.2 Which suburb is closer to the R72 road? 1.3 Calc

The scale is $1 : 50000$, meaning $1 \text{ cm}$ on the map represents $50000 \text{ cm}$ in reality.

$$
\text{Actual distance in cm} = \text{Map distance} \times \text{Scale factor}
$$
$$
\text{Actual distance in cm} = 8 \text{ cm} \times 50000 = 400000 \text{ cm}
$$

Since $1 \text{ km} = 100000 \text{ cm}$:
$$
\text{Actual distance in km} = \frac{400000 \text{ cm}}{100000 \text{ cm/km}} = 4 \text{ km}
$$
The actual distance between Milner Estate and Stirling is $\boxed{\text{4 km}}$.

There are 8 seats in each row (A, B, C, D).

$$
\text{Total seats} = \text{Number of rows} \times \text{Seats per row}
$$
$$
\text{Total seats} = 4 \times 8 = 32
$$
The number of seats inside the bus, excluding the driver's seat, is $\boxed{\text{32}}$.

Mr Dladla should move out of his seat (A5) into the aisle.

He should walk backwards along the aisle, passing rows B and C.

Upon reaching row D, he should cross the aisle to the left side of the bus and walk to seat D2.
