Ian flies a plane against a headwind for 4320 miles. The return trip with the wind took 12 hours less time. If the wind speed is 6 mph, how fast does Ian fly the plane when there is no wind?
-----------------------
t = 4320/(v - w) ----- t = time in hours, p = plane's airspeed, w = windspeed
t - 12 = 4320/(v + w)
=====================
t = 4320/(v - 6)
t - 12 = 4320/(v + 6)
-------
Can you solve for v?
