The figure shows a rectangular tank measuring 19 cm by 13 cm by 24 cm. Olivium poured 554 mℓ of water into the tank. Then, she turned on two taps at the same time to fill up the tank with water. Water was flowing from both taps at the same rate. After 5 minutes, both taps were turned off but 2.6 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 tank
= 19 x 13 x 24
= 5928 cm³
= 5928 mℓ

Volume of the remaining space after water was poured in
= 5928 - 554
= 5374 mℓ 

1 ℓ = 1000 mℓ
2.6 ℓ = 2600 mℓ

Volume of water contributed by 2 taps
= 5374 + 2600
= 7974 mℓ

Volume of water contributed by 1 tap
= 7974 ÷ 2 
= 3987 mℓ 

Rate of flow per minute
= 3987 ÷ 5
= 797.4 mℓ/min

Answer(s): 797.4 mℓ/min
