The velocity of the rain that is vertically falling downward is vrain
=20m/s.
The velocity of the wind that is blowing from west to east is vwind
=15m/s
as the person is walking 5m/s, hence, the final velocity from west to east is =10m/s
Now, the resultant velocity
v makes an angle θ with the vertical.
tanθ= vrain/vwind
=10/20
tan
=1/2
