GCSE Maths Practice: compound-measures

Question 10 of 10

This question checks correct calculation of average speeds.

‹

\( \begin{array}{l} \text{Which options correctly calculate average speed?} \end{array} \)

Select all correct options:

\( \text{120 km in 1.5 hours → 80 km/h} \) \( \text{210 km in 3.5 hours → 60 km/h} \) \( \text{180 km in 2.4 hours → 75 km/h} \) \( \text{150 km in 2.5 hours → 55 km/h} \)

Perform each division carefully to verify correctness.

Average speed = distance ÷ time. Ignore incorrect divisions.
