GCSE Maths Practice: inverse-proportion

Question 8 of 10

Find the time required for the journey at a different speed.

‹ ›

\( \begin{array}{l}\text{A journey takes 3 hours at 60 km/h.} \\ \text{How long would the same journey take at 90 km/h?}\end{array} \)

Choose one option:

\( \text{2 hours} \) \( \text{4 hours} \) \( \text{1.5 hours} \) \( \text{1 hour} \)

Use inverse proportion: when speed increases, travel time decreases for the same distance.
