Question 765508: A plane flying with a tail wind flew at a speed of 460 mph, relative to the ground. When flying against the tailwind, it flew at a speed of 340mph. graph the system to find the speed of the plane in calm air and the speed of the tailwind Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A plane flying with a tail wind flew at a speed of 460 mph, relative to the ground. When flying against the tailwind, it flew at a speed of 340mph. graph the system to find the speed of the plane in calm air and the speed of the tailwind
------------------
p + w = 460 mph
p - w = 340 mph
-------
Add and solve for "p":
2p = 800
p = 400 (speed of the plane in still air)
------
Solve for "w":
p + w = 460
400 + w = 460
w = 60 mph (speed of the wind)
