How far will an aircraft travel in 7.5 minutes with a ground speed of 114 knots?
A
14.25 NM.✓ Correct Answer
B
15.00 NM.
C
14.50 NM.
Explanation
Distance = groundspeed x time. At 114 knots the aircraft covers 114/60 = 1.9 NM per minute, so in 7.5 minutes it travels 1.9 x 7.5 = 14.25 NM (PHAK Ch. 16). 15.00 NM would correspond to 120 knots, and 14.50 NM does not match the given speed and time.
