write out the equation
please show the steps taken to solve the problem

A small airplane flies at a velocity of 145 km/h toward the south as observed by a person on the ground. the airplane pilot measures an air velocity of 172 km/h south. What is the velocity of the wind that affects the plane?

thnks

I barely remember anything from physics class last year, but wouldn't you subtract the difference between the two velocities? So the wind speed would be 27 km/h north, because it is hitting directly against the plane in the opposite direction. I think.
