### Solution

#### Question 2.1: Total Distance Travelled

To calculate the total distance a tourist will travel from Durban to Cape Town via Johannesburg and Bloemfontein, we need the distances between each pair of cities:

1. Distance from Durban to Johannesburg:
- From the distance table: 598 km

2. Distance from Johannesburg to Bloemfontein:
- From the distance table: 417 km

3. Distance from Bloemfontein to Cape Town:
- From the distance table: 998 km

Now, sum these distances to get the total distance travelled:
[tex]\[ \text{Total Distance} = 598 \text{ km} + 417 \text{ km} + 998 \text{ km} = 2013 \text{ km} \][/tex]

Thus, the total distance travelled by the tourist is 2013 km.

#### Question 2.2: Time Spent on the Road

To calculate the time spent on the road, we use the formula for time, which is:
[tex]\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \][/tex]

Given the total distance travelled is 2013 km and the average speed is 100 km/h, we can calculate the time spent on the journey as follows:
[tex]\[ \text{Time} = \frac{2013 \text{ km}}{100 \text{ km/h}} = 20.13 \text{ hours} \][/tex]

Thus, the time spent on the road for the journey is 20.13 hours.
