Level 3 PSLE Water could flow out of a tank through tap A and tap B. At first, Jim turned on tap A. After some time, he also turned on tap B so that more water flowed out. Later, he turned off both taps at the same time. The line graph shows the volume of water in the tank from 11 00 to 11 20.
What was the rate of flow of water from tap A in litres per minute?
How many litres of water flowed out of the tank throughout the period when both taps were turned on?
What was the rate of flow of water from tap B in litres per minute?

This figure is not drawn to scale. A rectangular glass tank 72 cm by 50 cm by 35 cm has 2 compartments, X and Y, with a water height of 30 cm in X and 15 cm in Y. A hole in the slider caused water to leak from X to Y. It was found that the water level in both compartments became the same after some time.
What is the height of water in the tank now?
It took 112 h for the water in both compartments to reach the same level. Assuming that water leaked at a constant rate, how much water flowed from X to Y in 1 minute? Express the answer to 1 decimal place in cm³.
