The figure shows a rectangular container measuring 32 cm by 40 cm by 28 cm. Marion poured 310 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 14 minutes, both taps were turned off but 2.9 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
= 32 x 40 x 28
= 35840 cm³
= 35840 mℓ

Volume of the remaining space after water was poured in
= 35840 - 310
= 35530 mℓ 

1 ℓ = 1000 mℓ
2.9 ℓ = 2900 mℓ

Volume of water contributed by 2 taps
= 35530 + 2900
= 38430 mℓ

Volume of water contributed by 1 tap
= 38430 ÷ 2 
= 19215 mℓ 

Rate of flow per minute
= 19215 ÷ 14
= 1372.5 mℓ/min

Answer(s): 1372.5 mℓ/min
