Pabola Neruda, a friend of the author, had come to Spain for the first time. The author compares Neruda to a Renaissance pope because Neruda behaviour was that of a childish manner. He walked through the crowd like an invalid elephant. Whenever he watched something, his mind had a child's curiosity of its inner workings. For the author, the world appeared to him as a substantial wind-up toy. However, the author compared Neruda to a Renaissance pope as he was insatiable and refined. Thus, the author could not imagine anyone closer to the idea one has of a renaissance pope other than Neruda.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
