Question 1161891
The distance between Montreal and Vancouver is approximately 3600 km. A plane flying from Montreal to Vancouver takes 5 h. A flight from Vancouver to Montreal takes 4 h. Assuming each plane flies at the same constant speed, calculate both the airspeed of the plane and the wind-speed. In which approximate direction is the wind blowing?
-----------
Find the 2 groundspeeds, upwind and downwind.
The plane's airspeed is the average of the 2.
----
The windspeed is the difference between airspeed and groundspeed.
