The return trip took an hour and twelve minutes ( the wind had not shifted nor change its speed). What was the speed of the wind? ** hour and a half=1.5 hr hour and twelve minutes=1.2 hr .. let x=wind speed Flying against the wind: speed of plane in still air-x=240/1.5 speed of plane in still air=240/1.5+x .. Flying with the wind: speed of plane in still air+x=240/1.2 speed of plane in still air=240/1.2-x .. 240/1.5+x=240/1.2-x 2x=240/1.2-240/1.5=.3(240)=72 x=36 mph ans: wind speed=36 mph
