Solve the following problems using the provided table and map. Question 1.5 involves calculating a total distance, and Question 1.6 asks for a grid reference.

Marcel travels from Cape Town to Port Elizabeth via Riversdale.
First, find the distance from Cape Town to Riversdale from the table.
Looking at the row for "Cape Town" and the column for "Riversdale", the distance is 305 km.
Next, find the distance from Riversdale to Port Elizabeth from the table.
Looking at the row for "Riversdale" and the column for "Port Elizabeth", the distance is 454 km.
The total distance is the sum of these two distances:

$$\text{Total distance} = \text{Distance (Cape Town to Riversdale)} + \text{Distance (Riversdale to Port Elizabeth)}$$ $$\text{Total distance} = 305 \text{ km} + 454 \text{ km}$$ $$\text{Total distance} = 759 \text{ km}$$

A. 305 km
B. 735 km
