An airplane flying at 120km/h due west moves into a region where the wind is blowing at 40km/h due east. If the plane's original vecotr velocity is Vplane, what is the expression for the plane's resulting velocity in terms of Vplane.

a. 1/3 >Vplane
b. 2/3>Vplane
c.1 Vplane
d. 80Vplane

Please explain how to find this- I thought I took 120-40 = 80 but D doesn't seem like the right answer
Thanks

• Physics -

This should say Physics-Typo error

• Ohysics -

it seems to me if V is 120, and the new velocity is 80, then 80/120 V is the expression, or resulting velocity=2/3 V
