GCSE Maths Practice: inverse-proportion

Question 5 of 10

Find the time required if fewer workers are used.

‹ ›

\( \begin{array}{l}\text{5 men take 15 hours.} \\ \text{How long for 3 men?}\end{array} \)

Choose one option:

\( \text{25 hours} \) \( \text{20 hours} \) \( \text{30 hours} \) \( \text{15 hours} \)

Use inverse proportion: fewer workers → more time, keeping total work constant.
