When distance is in nautical miles and speed is in knots, flight time in hours equals distance divided by _____.
Answer
groundspeed
Explanation
A knot is one nautical mile per hour, so dividing NM by kt produces hours. For example, 120 NM at 120 kt takes one hour. **Key takeaway:** `time = distance / GS` when units are NM and kt. **Glossary:** **Knot**: One nautical mile per hour; **GS**: Groundspeed.
