1. The problem statement, all variables and given/known data I am having difficulty thinking about this problem. How is speed related to average velocity? A car travels along a straight line at a constant speed of 47.0 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 33.5 mi/h. 2. Relevant equations 3. The attempt at a solution I have been trying to think of it in these terms (54 + Q) = 33.5 I know this isn't right....can I get some direction Thanks!!!
