An inverse variation can be represented by the equation xy=k or y=kx . That is, y varies inversely as x if there is some nonzero constant k such that, xy=k or y=kx where x≠0,y≠0 .
When you decrease your speed the time it takes to arrive at that location increase ,so the quatities are inversely proportional.An inverse variation can be represented by the equation xy=k or y =kx, that is, y vaies inveserly as x if there is some nonzero constant k such that ,xy=k or y=kx
