A person walks first at a constant speed of 5 m/s along a straight line from point A to
point B and then back along the line from B to A at a constant speed of 3 m/s. a. What is
her average speed over the entire trip? b. What is her average velocity over the entire
trip?
Homework Equations
The Attempt at a Solution
I am confused with the total distance between A and B. As far as I know for the average
speed I need to find the total distance from A to B and B to A. However how do I find
that? I also need the time as well.
