The figure shows a rectangular container measuring 46 cm by 19 cm by 14 cm. Esther poured 844 mℓ of water into the container. Then, she turned on two taps at the same time to fill up the container with water. Water was flowing from both taps at the same rate. After 12 minutes, both taps were turned off but 2.3 ℓ of water had overflowed and was collected in a tray. Find the rate of the flow of water of each tap in millilitres per minute.
Volume of the container
= 46 x 19 x 14
= 12236 cm³
= 12236 mℓ

Volume of the remaining space after water was poured in
= 12236 - 844
= 11392 mℓ 

1 ℓ = 1000 mℓ
2.3 ℓ = 2300 mℓ

Volume of water contributed by 2 taps
= 11392 + 2300
= 13692 mℓ

Volume of water contributed by 1 tap
= 13692 ÷ 2 
= 6846 mℓ 

Rate of flow per minute
= 6846 ÷ 12
= 570.5 mℓ/min

Answer(s): 570.5 mℓ/min
