A rectangular container measuring 60 cm by 55 cm by 30 cm was ¹₅ filled with water. Zoe turned on a tap at 10.23 p.m. to fill more water into the container. She turned off the tap at 10.45 p.m. The container was ²₃ 
filled with water. Given that the water flowed out of the tap at the same rate, find the volume of water that flowed out of the tap in a minute. Give your answer in litres.
Volume of water in the container at first
= ¹₅ x 60 x 55 x 30
= 19800 cm³

Volume of water in the container in the end
= ²₃ x 60 x 55 x 30
= 66000 cm³

Volume of water added into the container by the tap
= 66000 - 19800
= 46200 cm³

1000 mℓ = 1 ℓ
46200 mℓ = 46200 ÷ 1000 = 46.2 ℓ

From 10.23 p.m. to 10.45 p.m.: 22 min

Volume of water that flowed out of the tap in a minute
= 46.2 ÷ 22
= 2.1 ℓ 

Answer(s): 2.1 ℓ
