A 60-minute leg at 60 knots requires how many nautical miles?

• A. 30 NM
• B. 90 NM
• C. 60 NM
• D. 120 NM

Answer: (C)

Distance traveled equals speed times time. With speed in knots and time in hours, nautical miles = knots × hours. A 60-minute leg is 1 hour, so at 60 knots you cover 60 nautical miles in that hour. Therefore the distance is 60 NM. The other numbers would come from different times or speeds (e.g., 30 NM is 0.5 hour at 60 knots; 90 NM is 1.5 hours at 60 knots; 120 NM is 2 hours at 60 knots).
