An aircraft flies a distance of 150 NM in 1 hour and 15 minutes. Its average groundspeed is _____ kt.
Answer
120
Explanation
One hour 25 minutes is `$85/60$` hours. Therefore `$GS=110/(85/60)\approx77.6$` kt, which rounds to 78 kt. **Key takeaway:** Convert elapsed time to hours before calculating knots. **Glossary:** **Knot (kt)**: one nautical mile per hour.
