1. The problem statement, all variables and given/known data An airplane flies 142 mi/hr with respect to the air. On this day, the air is moving at 52 mi/hr due north with respect to the ground. What would be the velocity of the plane with respect to the ground,vpg, if the plane were pointed in each of the following directions? How long would it take the plane to cross a state whose eastern and western borders are parallel lines 320 mi apart if the nose of the plane were pointed 45 degrees east of north? The wind is still blowing. 2. Relevant equations trig functions. Pythagorean thereom 3. The attempt at a solution Okay, so I have tried doing the problem where when I do 45 degrees east of north, my velocity for the plane is 182.3 mi/h, and then I divide 320 by 182.3 and I get around 1.76, but that is not the correct answer why? Any help would be appreciated.
