A 250N effort force is exerted on an ideal machine with an actual mechanical advantage of 4. If the effort distance is 3 meters, calculate the resistance distance. (Hint: You'll have trouble solving this in one step. But think about what measurement you could solve for in one step, and if that measurement would help answer the question.) I
