Answer 3

how much are you writing

Answer 4

You essentially need to evaluate the slopes throughout, which explains velocity, because

\(v=\frac{Δx}{Δt}\)

At first they're walking in one direction at some velocity v. Then the slope is 0, which means the velocity is 0. That means that they are still. Now, they return back at a slope where the magnitude is the same yet the sign is opposite. This means that they are walking in the opposite direction.

so which one is it
