Is it radius or circumference?
X - y = 2400/6 = 400 where x = speed of plane and y = speed of wind.
x + y = 2400/5 = 480 - flying with the wind
adding the 2 equations
2x = 880
x = 440
Speed of the plane with no wind = 440 mph
Answer:y^1=3 ,y^2=9 if im wrong sorry im wrong but hope you get an a
<span>Selection A is correct</span>
