Answer:
The actual velocity of the plane is 159 mph.
Step-by-step explanation:
It is given that, a private plane is traveling due east at a rate of 155 mph. A south wind is blowing 35 mph.
Let v₁ is the velocity of private plane and v₂ is the velocity of wind. We have to find the actual velocity of the plane. So, the resultant is given by :
[tex]v=\sqrt{v_1^2+v_2^2}[/tex]
[tex]v=\sqrt{(155\ mph)^2+(35\ mph)^2}[/tex]
v = 158.9 mph
or
v = 159 mph
Hence, the correct option is " 159 mph ".
