Answer 1

Airplane speed = <270,0>
(components in the x,y directions)

Wind speed 75 km/hr eastwards
=<75,0>

Resultant speed
= <270,0>+<75,0> = <345,0>
= 345 km/hr eastwards.

Wind speed blowing 75 km/h west
Resultant
=<270,0>+<-75,0>
=<195,0>
=195 km/hr eastwards

Wind blowing north
Resultant speed
=<270,0>+<0,75>
=<270,75>
=√(270²+75²)
=280.2 km/h approximately
