**Jeff**, Tuesday, February 19, 2013 at 9:41pmThink of a right triangle. The airport is the vertex of the right angle. Plane A is 70 miles north (Straight up). Plane B is 168 miles East (Straight right). From plane A to B would be side C of the right triange.

C^2 = A^2 + B^2

C = sqrt (A^2 + B^2)

C = sqrt (70^2 + 168^2)

C = sqrt (33124)

C = 182 miles
