It takes Faucet T 30 minutes to fill a container measuring 17 cm by 11 cm by 15 cm completely while it takes Faucet Z only 30 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 3 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 T to fill the container:

30 min → 1 tank
1 min → ¹₃₀ tank

Time taken by Faucet Z to fill the container:
30 min → 1 tank
1 min → ¹₃₀ tank

Volume of the container
= 17 x 11 x 15
= 2805 cm³

Volume of 5 cubic cubes
= 5 x (3 x 3 x 3)
= 135 cm³

Time taken by Faucet T and Faucet Z to fill a container:
1 min → ¹₃₀ + ¹₃₀ =²₃₀ = ¹₁₅ container

¹₁₅ container → 1 min
1 container → 1 ÷ ¹₁₅ = 1 x ¹⁵₁ = 15 min

Remaining volume of the container to be filled by both faucets 
= 2805 - 135
= 2670 cm³

Time taken to fill the container
= ²⁶⁷⁰₂₈₀₅ x 15
= 14.27807486631
≈ 14.28 min

Answer(s): 14.28 min
