1. Take a guess, at least. You wont' learn anything by haviong us provide answers.

1. The plot is time (horizontal) against distance (vertical axis). What changes along the vertical axis? What doesnt change?

2. If the slope is 1, changes in distance equal changes in time along the line. What does that tell you?
