A plane traveled 812 miles to Austin and back. The trip there was with the wind. It took 7 hours. The trip back was into the wind. The trip back took 14 hours. FInd the speed of the plane in still air and the speed of the wind.
Going TO Austin 812 / 7 = 116 m/hr
going BACK 812/14 = 58
(116+58)/2 = plane speed = 87 m/hr then wind is 116 - 87 = 29 m/hr
