City hall and the two planes locations become vertices of a right triangle. Hypotenuse is the distance between the two planes.

Eastbound traveled 2 hours.
600%2A2 eastward

Northbound traveled 1 hour.
500%2A1 northward

Distance between the two planes at 8AM,
sqrt%28%28600%2A2%29%5E2%2B500%5E2%29

sqrt%281440000%2B250000%29
