At an airport, a flight controller is in a tower 45m above the ground. She observes an airplane flying at a constant altitude at an angle of elevation of 14 degrees from her line of sight. Seven seconds later, the airplane flies directly overhead.
If the airplane has a constant speed of 370 KM/H, what distance, in meters, did it cover between the time the flight controller first observed the airplane to when it passed overhead?"
