 Question 89115: A plane can fly 1240 miles with a certain tail wind in 4 hours. When flying against a wind with the same velocity it can fly 1500 in 6 hours. What is the planes speed in still air?Answer by askmemath(368)   (Show Source): You can put this solution on YOUR website!Let the speed of the plane = S Let speed of Wind = W Now speed of plane per hour = 1240/4 = 310 Since the tail wind aids the plane S+W = 310 Similarly S-W = 1500/6 = 250 S+W = 310 S-W = 250 Adding both 2S = 560 S = 280 Therefore speed of plane = 280
