After 2 hours, Plane North is \"150%282%29=300\" miles north of the airport, and Plane West is \"200%282%29=400\" miles west of the airport. The two distances form the legs of a right triangle. The distance between them is the hypotenuse of the triangle and can be determined using Pythagorean theorem.
