GCSE Maths Practice: inverse-proportion

Question 10 of 10

Find the time needed when using more pipes to fill a tank.

‹

\( \begin{array}{l}\text{Two pipes fill a tank in 12 minutes.} \\ \text{How long will it take 4 pipes?}\end{array} \)

Choose one option:

\( \text{6 minutes} \) \( \text{8 minutes} \) \( \text{4 minutes} \) \( \text{3 minutes} \)

Use inverse proportion: if the number of pipes doubles, the time halves for the same tank volume.
