What is the definition of a related rates problem?

Question

anonymous · Answer

I don't know about the exact definition but basically they are problems that require you to find a relationshi between the rate of change of two different things. For example if a cone shaped water tank is being drained of water at 2m^3 a second and the tank is 16m^3 find rate of change of the height of the water after 20 seconds. You see what I am saying?
