An airplane encountered a head wind during a flight between Joppetown and Jawsburgh which took 5 hours and 30 minutes. The return flight took 5hours. If the distance from Joppetown to Jawsburgh is 1600
miles, find the airspeed of the plane (the speed of the plane in still air) and the speed of the wind, assuming both remain constant.

Vp*t = 1600.
Vp*5 = 1600, Vp = 320 mi/h. in still air.
(Vp-Vw)*5.5 = 1600.
5.5Vp - 5.5Vw = 1600.
5.5*320 - 5.5Vw = 1600, Vw = ?.
