Answer 1

The answer for this city chart is 145

BUT there is another city chart with a different answer (319) make sure you check if your city chart and this city chart are the same

Explanation:

Answer 2

The range for the cities in the south is 145 larger than the range for the cities in the north.

We find the range by subtracting the highest and lowest values; in the North, we have:
305 - 58 = 247

In the South, we have:
503 - 111 = 392

The difference in the ranges is 392 - 247 = 145.
