61. TAS is 180 kt with a 25 kt headwind for 2 h 25 min. What distance is flown?
Answer
375 NM
Explanation
GS is $180−25=155$ kt. The elapsed time is about 2.417 h, so distance is approximately $155×2.417=375$ NM. **Key takeaway:** Distance equals GS multiplied by time. **Glossary:** Headwind: wind component opposing travel.
