Answer: 190 miles/304 km ;

Anonymous · Answer

The actual distance between Alexandria and Roanoke is 190 miles, based on the map scale of 2 cm = 50 miles. This was calculated by determining that each cm on the map represents 25 miles, and then multiplying that by the map distance of 7.6 cm. Therefore, the calculation gives: 7.6 cm × 25 miles/cm = 190 miles.
