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 12040 = 80 but D doesn't seem like the right answer
Thanks

Joel,
This should say PhysicsTypo error

bobpursley,
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
Your choice of answers are nonsense. Ask your teacher what they mean. I hope this is not a college course.
