In my copy of H&R the phrase "change in displacement" does not appear in the sections defining velocity, speed and acceleration. Rather, they refer to " The DISPLACEMENT VECTOR describing the CHANGE in position ...", and "... the displacement in a small interval of time ..." etc. I guess Curtis just wasn't careful in transcribing these definitions.
