Question

An aircraft heads north at 320km/h relative to the wind . The wind velocity is 80km/h from the north. Find the velocity of the aircraft relative to the aircraft relative to the ground

Answer 1

velocity of the aircraft relative to the ground:

$v=v_1-v_2$

where v₁ is velocity of the aircraft relative to the wind,

v₂ is wind velocity

$v=320-80=240$ km/h
