Taking into account the wind blowing

When the plane you re traveling in has a good tailwind, you make even better time than anticipated. A headwind slows things down a bit. The blowing wind is taken into consideration when figuring how fast a plane is moving and in what direction it s actually heading. 

The answer that r = -270 is discarded as being extraneous. The northbound plane is traveling at 130 miles per hour.
