The figure shows a rectangular tank measuring 17 cm by 50 cm by 12 cm. Tammy poured 752 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 12 minutes, both taps were turned off but 4.4 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
= 17 x 50 x 12
= 10200 cm³
= 10200 mℓ

Volume of the remaining space after water was poured in
= 10200 - 752
= 9448 mℓ 

1 ℓ = 1000 mℓ
4.4 ℓ = 4400 mℓ

Volume of water contributed by 2 taps
= 9448 + 4400
= 13848 mℓ

Volume of water contributed by 1 tap
= 13848 ÷ 2 
= 6924 mℓ 

Rate of flow per minute
= 6924 ÷ 12
= 577 mℓ/min

Answer(s): 577 mℓ/min
