Question: Scenario 2: When assessing the shortest route between two points on a street grid, what is generally the most efficient method?

Answer options:

• Always follow major highways, regardless of distance
• Calculate the 'as-the-crow-flies' distance (direct line) ✅ Count the number of blocks horizontally and vertically, then sum them (Manhattan distance)
• Avoid all turns to save time

Correct answer: Count the number of blocks horizontally and vertically, then sum them (Manhattan distance)

Explanation: On a strict street grid, the shortest route between two points is often found by summing the horizontal and vertical block counts, which is known as Manhattan distance. This accounts for the necessity of following streets. The correct answer is "Count the number of blocks horizontally and vertically, then sum them (Manhattan distance)".
