Airplane Distance and Angles Analysis

The video tutorial explains how to calculate the distance between two airplanes using heading and bearing information. Two airplanes leave an airport at the same time, one flying on a bearing of north 40 degrees west at 110 mph and the other on a bearing of south 30 degrees west at 190 mph. The tutorial uses the law of cosines to find the distance between the planes after one hour, considering the angles and speeds. The final calculated distance is 250 miles.
