A rectangular tank measuring 70 cm by 60 cm by 24 cm was ¹₆ filled with water. Shiyun turned on a tap at 4.14 p.m. to fill more water into the tank. She turned off the tap at 4.28 p.m. The tank 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 tank at first
= ¹₆ x 70 x 60 x 24
= 16800 cm³

Volume of water in the tank in the end
= ²₃ x 70 x 60 x 24
= 67200 cm³

Volume of water added into the tank by the tap
= 67200 - 16800
= 50400 cm³

1000 mℓ = 1 ℓ
50400 mℓ = 50400 ÷ 1000 = 50.4 ℓ

From 4.14 p.m. to 4.28 p.m.: 14 min

Volume of water that flowed out of the tap in a minute
= 50.4 ÷ 14
= 3.6 ℓ 

Answer(s): 3.6 ℓ
