    Very similar to your other https://www.physicsforums.com/showthread.php?t=383183".

    Assign some distance, say 1 meter, between the blocks, then use that to measure the total length of the rope.

    Then move the block to 2 meters apart and remeasure the total distance of the rope. How much did the length of the rope change compared to the distance of the block.

    I think the rope moves 3 times faster than the blocks.
