...that day and distance travelled bothways? An airplane cruises at 120km/h in still air.One day,when the wind was blowing steady from the west, the airplane travelled west (flying into the wind) and landed at it's destination after 1.5h.The airplane's return trip(flying with the wind) was only 1.0h long.On both legs,the airplane travelled at it's cruising speed (measured with respect to the air surrounding the airplane).
