text: Use the equation:\n\nWork = Force*Distance\n\nThe machine exerts a work of: (800 N)(6 m) = 4800 J.  In this problem you are calculating the resistance force that would create the same amount of work.  Therefore:\n\nWork_resistance = Force_resistance*Distance\n\nDistance = (4800 J)/(200 N) = 240 m --------> Answer B\n\n---------\n\nHope this helps
