**bobpursley**, Thursday, September 23, 2010 at 7:33pmat t=38, one wants the separation be 1 meter.

distance(38)=speedgazelle*38-speedcheeta(38)+intialseparation

change the speeds to m/s, then

1=xxx*38-YYY*38+initialseparation

solve for separation

they obviously solved for separation to be 0 at 38s, which doesn't make sense because the gazelle would die.. but do you think d then is the right answer?
