GCSE Maths Practice: units-and-conversions

Question 7 of 10

This question tests knowledge of the speed formula: speed = distance / time.

‹ ›

\( \begin{array}{l}\text{Which formula gives the calculation for speed?}\end{array} \)

Choose one option:

\( \text{Speed} = \frac{\text{Distance}}{\text{Time}} \) \( \text{Speed} = \text{Distance} \times \text{Time} \) \( \text{Speed} = \text{Time} \div \text{Distance} \)

Use Speed = Distance ÷ Time. Check units.

Speed measures how fast something moves. It is calculated as distance divided by time. For example, if a car travels 180 km in 2 h, speed = 180 ÷ 2 = 90 km/h. Students should ensure distance and time are in compatible units. Understanding speed is essential in physics, everyday travel planning, and problem-solving.
