Flying with the wind (p+w) a plane went 327 mph. Flying into the same wind (p-w) the plane
only went 289
mph. What is the speed of the wind? How fast would the plane go if there were no wind?

Lets set up the equation:

p + w = 327  -- equation 1

p - w = 289 -- equation 2

equation 1 + equation 2

2p = 616

p = 308

Thus the plane flies at 308 mph without the wind.

Hope that helps!
