Explain the reasons why the airline will fly the route by the budget allocated.

Step 1: Identify the locations and measure the map distance between Johannesburg International Airport (JNB) and King Shaka International Airport (DUR) using a ruler or straight edge.

Measured map distance = $4.8$ cm (as per map).

Step 2: State the map scale.

Scale = $1 : 1\,500\,000$

This means $1$ cm on the map = $\frac{1\,500\,000}{100}$ m = $15\,000$ m = $15$ km.

Step 3: Calculate the actual flying distance.

(Note: This is straight-line distance; actual flight path may vary slightly.)

Flying distance: $\mathbf{72\ km}$

Step 4: For road distance JNB to DUR (use provided route or scale for curved road: measured $6.2$ cm).

(Note: Actual road distance approximately $600$ km; adjust scale if map-specific. Use given scale bar for precision.)

Step 5: Calculate flying time. Aircraft speed = $800$ km/h (economy jet).

Formula: $t = \frac{d}{v}$

Convert: $0.09 \times 60 = 5.4$ minutes $\approx 5$ minutes.

Flying time: $\mathbf{5\ minutes}$

Step 6: Calculate driving time. Average speed = $110$ km/h (N3 highway).

Use actual road distance $600$ km (standard).

$0.45 \times 60 \approx 27$ minutes.

Driving time: $\mathbf{5\ hours\ 27\ minutes}$

1.1 Flying distance: 72 km
1.2 Road distance: 600 km
1.3 Flying time: 5 min
1.4 Driving time: 5 h 27 min
