The 201 rungs monkey bar hangs on the mid rung to keep balanced horizontally. Four monkeys are leveled ..(see illustration)
the 3 lbs stands and the 1 lbs hangs on the left end while the 2 lbs stands and another 3 lbs hangs at 20 rungs away from right end.

If  they all move (swing or walk) to the far ends at uniform rate of 1 rung/sec (they can pass each other),one of them shall move
at different uniform speed to keep the monkey bar from tilting. What then is the speed of the (fast or slow) monkey??
