His speed is non uniform because time is same but distance is changing so speed changes.
His speed along large side = 8/4
4 min = 240 seconds
So, 8/240
= 0.033 m/s
along smaller side
4/240
= 0.016 m/s
Average speed = 0.033+0.016/2
= 0.049/2
= 0.0325 m/s

Answer:The answer is second class lever.
In second class levers, load lies between the fulcrum and the effort.
However, the load is not positioned at the exact center. It is placed more towards the fulcrum and away from the effort. A second class lever always multiplies a force.
There are many examples of second class levers in day to day life. Some common examples are bottle openers, nut crackers, doors and wheel barrows.
