Answer:
Distance between the cities on the map = 101, 000 miles
Explanations
According to the question :
[tex]\begin{gathered} \frac{1}{2}\text{inches = 1010 miles} \\ \text{That is,} \\ 0.5\text{ inches = 1010 miles} \end{gathered}[/tex]Therefore, 1 inch = 2020 miles.
This means that 1 inch represents 2020 miles
The distance between the two cities = 50 inches
Since 1 inch = 2020 miles
50 inches will represent (50 x 2020) miles = 101,000 miles
The distance between the two cities on the map = 101, 000 miles
