A student uses a lever to lift a heavy boulder as shown in the diagram below. An effort of 150 N is applied downward at one end of the lever to balance the boulder (load) of 750 N at the other end.

Diagram showing a balanced lever system. A horizontal lever rests on a triangular pivot. On the right side of the pivot, a boulder (load) exerts a downward force of 750 N, and the distance from this load to the pivot is labeled as 0.40 m. On the left side of the pivot, a downward force (effort) of 150 N is applied at the end of the lever. The distance from this effort to the pivot is unknown.

Calculate the distance between the effort and the pivot.
