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.
H%5E2=N%5E2%2BW%5E2
H%5E2=300%5E2%2B400%5E2
H%5E2=90000%2B160000
H%5E2=250000
H=500
They would be 500 miles apart.
