Tank N measuring 41 cm by 30 cm by 40 cm contains 6.8 ℓ of water. It is being filled with water flowing from Tap P at 0.5 ℓ/min and Tap Q at 696 mℓ/min. Both taps are turned on at the same time. How long does it take to fill up Tank N till it is 60% full? Correct the answer to 1 decimal place.
Volume of Tank N at 60% full
= 41 x 30 x 40 x 60%
= 54 x 14 x 25 x ⁷⁵₁₀₀
= 29520 cm³ 

1 ℓ = 1000 mℓ = 1000 cm³ 
6.8 ℓ = 1000 x 6.8 = 6800 cm³
0.5 ℓ = 1000 x 0.5 = 500 cm³

Volume of water to fill Tank N
= 29520 - 6800
= 22720 cm³ 

Volume of water from the two taps per minute
= 500 + 696
= 1196 cm³/min

Time taken to fill Tank N to 60%
= 22720 ÷ 1196
≈ 19 min

Answer(s): 19 min
