Hello Timmyevans20002owv8o2,
How are you doing? I am sorry your question has not been answer so quickly, however here it is. lets analyse this question; you should know that 'm/s' is a measure of speed, and the phrase 'to the north' is describing a direction. for this question we don't even need to go into 'vector' quantities. Time will be given by a measurement on a timer ex: 40 seconds and saying someone was traveling at some speed is not going to give us their time. 'Acceleration' by definition is a change in speed and the speed given in the statement is constant. Position is something very hard to describe anyway. Now 'velocity' is speed with a direction (vector) it can be given a value(magnitude) and a direction and we have both speed and the direction. therefore your answer is 'velocity'.
Thank you,
Darian D.
