The climb angle (angle of elevation) of an airplane taking off is 20°. If the airplane maintains that angle until it reaches cruising altitude, what is the approximate horizontal ground distance from that airplane to the point of takeoff when the airplane has reached its cruising altitude of 30,000 feet? (Remember that 1 mile = 5280 feet) 107 miles ground distance from that airplane to the point of takeoff when the airplane has reached its cruising altitude of 30,000 feet?
