Watching a Helicopter Take Off At a distance of 58 ft from the pad, a man observes a helicopter taking off from a heliport. If the helicopter lifts off vertically and is rising at a speed of 45 ft/sec when it is at an altitude of 124 ft, how fast is the distance between the helicopter and the man changing at that instant? (Round your answer to one decimal place.)
