What are the miles from IGB to GLH?

• A. 120 miles
• B. 124 miles
• C. 130 miles
• D. 110 miles

Answer: (B)

The main idea here is the straight-line distance between two airports, known as the great-circle distance. To find it, you use each airport’s coordinates and compute the shortest path over the globe, rather than routing along roads or airways. For IGB to GLH, doing that calculation gives about 124 miles, which best matches the direct separation between the two locations. The other numbers don’t reflect the actual direct distance between these airports, so they don’t fit as the direct-distance answer.
