The angle of elevation of a hot air balloon, climbing vertically, changes from 25° at 10:00am to 60° at 10:02am. The point of observation of the angle of elevation is situated 300 meters away from take-off point. What is the upward speed, assumed constant, of the balloon? h₂ 60° @ 10:02 am 25° @10:00 am 300 meters h₁
