1. The problem statement, all variables and given/known data A hiker travels south a long a straight path for 1.5 h with an average velocity of .75 km/h. then travels south for 2.5 h with an average velocity of .90 km/h. What is the hiker's displacement for the total trip? 2. Relevant equations 3. The attempt at a solution For the answer I have 3.4 km to the south. but hm, I think I copied the question wrong. I have a feeling that I was supposed to have another coordinate sign besides south... so I'm not sure.
