The table is the key to organization!  Try to figure out the times of each ship.  The times are known.  Walter (W) left four hours earlier and then Sadie (S) left and traveled for 2 hours.  Fill out the table for rate and time and then Fill out the Distance by using the formula rt=D.  The total distance is 230, this is your equation that you can use to solve.
