It takes Faucet Q 30 minutes to fill a container measuring 19 cm by 12 cm by 13 cm completely while it takes Faucet W only 15 minutes. How long will it take to completely fill the container with water if both faucets are turned on at the same time and 5 cubic cubes of edges 2 cm, filled with water, are poured into the container? Leave the answer in minutes and round off to 2 decimal places.
Time taken by Faucet Q to fill the container:

30 min → 1 tank
1 min → ¹₃₀ tank

Time taken by Faucet W to fill the container:
15 min → 1 tank
1 min → ¹₁₅ tank

Volume of the container
= 19 x 12 x 13
= 2964 cm³

Volume of 5 cubic cubes
= 5 x (2 x 2 x 2)
= 40 cm³

Time taken by Faucet Q and Faucet W to fill a container:
1 min → ¹₃₀ + ¹₁₅ =³₃₀ = ¹₁₀ container

¹₁₀ container → 1 min
1 container → 1 ÷ ¹₁₀ = 1 x ¹⁰₁ = 10 min

Remaining volume of the container to be filled by both faucets 
= 2964 - 40
= 2924 cm³

Time taken to fill the container
= ²⁹²⁴₂₉₆₄ x 10
= 9.8650472334683
≈ 9.87 min

Answer(s): 9.87 min
