Answer:
8 cm; from the table
Explanation:
The equation gives the ground distance in terms of the map distance, so would have to be solved for x to be used to find map distance.
The graph is not shown.
The table appears correct, and includes the value 32 km for a map distance of 4 cm. The ground distance of interest is 64 km, which is twice that table value. That means the map distance will be twice the corresponding table value: 2×4 cm = 8 cm.
The distance from Town A to Town B is represented on the map by 8 cm.
