A rectangular tank measuring 55 cm by 35 cm by 24 cm was ¹₇ filled with water. Wendy turned on a tap at 6.13 p.m. to fill more water into the tank. She turned off the tap at 6.31 p.m. The tank was ⁴₇ 
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
= ¹₇ x 55 x 35 x 24
= 6600 cm³

Volume of water in the tank in the end
= ⁴₇ x 55 x 35 x 24
= 26400 cm³

Volume of water added into the tank by the tap
= 26400 - 6600
= 19800 cm³

1000 mℓ = 1 ℓ
19800 mℓ = 19800 ÷ 1000 = 19.8 ℓ

From 6.13 p.m. to 6.31 p.m.: 18 min

Volume of water that flowed out of the tap in a minute
= 19.8 ÷ 18
= 1.1 ℓ 

Answer(s): 1.1 ℓ
