Question

Kathir then drives an airplane is headed north with a constant velocity of 450 km/h. The plane encounters a wind from the west at 100 km/h. In what direction will the plane travel and in 3 h how far will the plane travel?

Answer 1

Draw a diagram. It should be clear that the resultant speed is
√(450^2 + 100^2) = _____
and distance = speed * time
The direction will be NE at an angle θ where
tanθ = 100/450
