Siphiwe and Matete are travelling from Pretoria to the Kruger Park which is 3 km from Hazyview. They are driving at the speed of 120 km/h. They left Pretoria at 01h30 and had to rest for 10 minutes after every 100 km drive.

The distances are:
Pretoria to Witbank: $120 \text{ km}$
Witbank to Lydenburg: $280 \text{ km}$
Lydenburg to Whiteriver: $140 \text{ km}$
Whiteriver to Hazyview: $15 \text{ km}$
Hazyview to Kruger Park: $3 \text{ km}$

The total distance by road from Pretoria to the Kruger Park is $\boxed{558 \text{ km}}$.

From part (i), the total distance is $558 \text{ km}$.

Siphiwe drives the 1st $100 \text{ km}$.
Matete drives the 2nd $100 \text{ km}$.
Siphiwe drives the 3rd $100 \text{ km}$.
Matete drives the 4th $100 \text{ km}$.
Siphiwe drives the 5th $100 \text{ km}$.
Remaining distance = $558 \text{ km} - (5 \times 100 \text{ km}) = 558 \text{ km} - 500 \text{ km} = 58 \text{ km}$.
Matete drives the remaining $58 \text{ km}$.

Siphiwe's total distance = $100 \text{ km} + 100 \text{ km} + 100 \text{ km} = 300 \text{ km}$.
Matete's total distance = $100 \text{ km} + 100 \text{ km} + 58 \text{ km} = 258 \text{ km}$.
Siphiwe drives $\boxed{300 \text{ km}}$ and Matete drives $\boxed{258 \text{ km}}$.

Total distance = $558 \text{ km}$ (from part i).
Average speed = $120 \text{ km/h}$.

$0.65 \text{ hours} \times 60 \text{ minutes/hour} = 39 \text{ minutes}$.
So, the driving time is $4 \text{ hours and } 39 \text{ minutes}$.

The problem states they stop once for $30 \text{ minutes}$ to rest.

Since $69 \text{ minutes} = 1 \text{ hour and } 9 \text{ minutes}$:

Departure time = $01\text{h}30$.

They reach the Kruger Park at $\boxed{06\text{h}39}$.
