Tank P measuring 44 cm by 25 cm by 29 cm contains 6.1 ℓ of water. It is being filled with water flowing from Tap Q at 0.3 ℓ/min and Tap R at 595 mℓ/min. Both taps are turned on at the same time. How long does it take to fill up Tank P till it is 64% full? Correct the answer to 1 decimal place.
Volume of Tank P at 64% full
= 44 x 25 x 29 x 64%
= 54 x 14 x 25 x ⁷⁵₁₀₀
= 20416 cm³ 

1 ℓ = 1000 mℓ = 1000 cm³ 
6.1 ℓ = 1000 x 6.1 = 6100 cm³
0.3 ℓ = 1000 x 0.3 = 300 cm³

Volume of water to fill Tank P
= 20416 - 6100
= 14316 cm³ 

Volume of water from the two taps per minute
= 300 + 595
= 895 cm³/min

Time taken to fill Tank P to 64%
= 14316 ÷ 895
≈ 16 min

Answer(s): 16 min
