EASA NAV(A)basic
An aircraft travels 100 km in 56 minutes. What is its groundspeed?
Answer
107 km/h
Explanation
Convert 56 minutes to hours: 56/60 = 0.933 hours. GS = 100/0.933 ≈ 107 km/h. The question asks for km/h, so a knot option is not the matching unit. **Key takeaway:** Speed equals distance divided by elapsed time in compatible units. **Glossary:** **Groundspeed**: Ground distance travelled per unit time.
