The figure shows a rectangular tank measuring 50 cm by 38 cm by 20 cm. Jen poured 746 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 10 minutes, both taps were turned off but 1.2 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
= 50 x 38 x 20
= 38000 cm³
= 38000 mℓ

Volume of the remaining space after water was poured in
= 38000 - 746
= 37254 mℓ 

1 ℓ = 1000 mℓ
1.2 ℓ = 1200 mℓ

Volume of water contributed by 2 taps
= 37254 + 1200
= 38454 mℓ

Volume of water contributed by 1 tap
= 38454 ÷ 2 
= 19227 mℓ 

Rate of flow per minute
= 19227 ÷ 10
= 1922.7 mℓ/min

Answer(s): 1922.7 mℓ/min
