 Question 384346: at a height of h meters, you can see V kilometers to the horizon. These numbers are related by the equation V = 3.5 sqrt h. A person can see 385 km to the horizon from an airplane window. How high is the airplane?Answer by stanbon(57984)   (Show Source): You can put this solution on YOUR website! at a height of h meters, you can see V kilometers to the horizon. These numbers are related by the equation V = 3.5 sqrt h. A person can see 385 km to the horizon from an airplane window. How high is the airplane? ---- V = 3.5*sqrt(h) 385 = 3.5*sqrt(h) sqrt(h) = 110 h = 110^2 = 12,100 meters ======================= ======================= Cheers, Stan H.
