The figure shows a rectangular tank measuring 37 cm by 22 cm by 25 cm. Nora poured 676 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 11 minutes, both taps were turned off but 3.8 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
= 37 x 22 x 25
= 20350 cm³
= 20350 mℓ

Volume of the remaining space after water was poured in
= 20350 - 676
= 19674 mℓ 

1 ℓ = 1000 mℓ
3.8 ℓ = 3800 mℓ

Volume of water contributed by 2 taps
= 19674 + 3800
= 23474 mℓ

Volume of water contributed by 1 tap
= 23474 ÷ 2 
= 11737 mℓ 

Rate of flow per minute
= 11737 ÷ 11
= 1067 mℓ/min

Answer(s): 1067 mℓ/min
