An airplane takes 9 hours to travel a distance of 8424 kilometers against the wind. The return trip takes 8 hours with the wind. What is the rate of the plane in still air and what is the rate of the wind?
Added by James H.
Step 1
Step 1:** Rate against the wind = (Distance / Time) - Wind speed Rate against the wind = 8424 km / 9 hours = 936 km/h Rate with the wind = (Distance / Time) + Wind speed Rate with the wind = 8424 km / 8 hours = 1053 km/h ** Show more…
