A fixed volume of water flows into a rectangular water tank such that the rate of water flow can be changed by using different pipes. Which of the following relations represent(s) inverse proportions?
A fixed volume of water flows into a rectangular water tank such that the rate of water flow can be changed by using different pipes. Which of the following relations represent(s) inverse proportions?
The correct options are
B The volume of the pipe used and time taken to fill the tank.
C The rate of water flow and the time taken to fill the tank
In direct proportion , as one quantity increases , the other quantity increases
In inverse proportion , as one quantity increases, the other quanitity decreases
(i) As the rate of water flow increases, the height of the water level increases.( direct proportion )
(ii)As the rate of water flow increases, the time taken to fill the tank decreases. ( inverse proportion )
(iii)If the volume of the pipe used is increased, then the time taken to fill the tank is decreased. ( inverse proportion )
(iv)If the number of pipes used is increased, then the amount of water flow into the tank is also increased.( direct proportion )
