The area of the small piston of a hydraulic press is 4cm squared and the large piston is 500cm squared.

The area of the small piston of a hydraulic press is 4cm squared and the large piston is 500cm squared. At what speed the larger piston of this press rises if the small piston descends at a speed of 25 cm / s.

Let us find how many times the area of the piston of a large cylinder, equal to 500 cm², is greater than the area of the piston of a small cylinder, equal to 4 cm²:
500: 4 = 125 times.
Let’s find the speed with which the large piston will rise if the small one descends at a speed of 25 cm / s:
25: 125 = 0.2 cm / s.
Answer: The speed of the large cylinder is 0.2 cm / s.
