Homework Help: Relative Velocity

  1. Nov 1, 2005 #1
    A plane can fly 100km/h in still air. It flies into a 10 km/h headwind. What is its groundspeed?

    Would this answer be 100 - 10 = 90km/h? Just making sure i didn't overlook something.

    As long as we're talking about 1 dimension, then you are correct.
