A plane leaves Toronto and flies with an airspeed of 2.20 x 10^2 km/h always pointing due east. A wind is blowing from the north at 8.0 x 10^1 km/h.

a) What is the plane's velocity relative to the ground?

b) What is the plane's displacement from Toronto after flying for 2.5h?

For (a), draw and solve a vector diagram.

Air velocity + Airspeed vector = Ground speed vector

For (b) Multiply the Ground speed vector by 2 hours, and the answer will be the displacement vector.

I will be glad to critique your work.
