Since 1/2 inch = 100 miles, 1 inch = 200 miles. If we know the number of inches between cities X and Y on the map, then we know the actual distance between cities X and Y.
Statement One Alone:
City X is 3 inches from City Y on the map.
Since City X is 3 inches from City Y on the map, City X is actually 600 miles from City Y.
Statement one alone is sufficient to answer the question.
Statement Two Alone:
Cities X and Y are each 300 miles from City Z.
We know the distance between X and Z and the distance between Y and Z; however we don’t know how these cities are positioned relative to each other. For instance, if the three cities are on a line and Z is between X and Y, then the distance between X and Y is 600 miles. On the other hand, if the three cities are not on a line and the triangle formed by these three cities is an equilateral triangle, then the distance between X and Y is also 300 miles. Statement two alone is not sufficient to answer the question.
Answer: A
