The cards Question In maths, what is a rate? Tap to flip Answer A relationship between two units, e.g. miles per hour relates distance and time. Question What is an exchange rate? Tap to flip Answer The rate at which one currency is exchanged for another. Question Why are two currencies in proportion? Tap to flip Answer Because they have a constant multiplicative relationship.

Tap to flip Answer The total units used since the meter was installed. Question How is speed measured? Tap to flip Answer As the distance travelled per unit of time. Question How is pace measured? Tap to flip Answer As the time taken per unit of distance. Question How do you calculate average speed? Tap to flip Answer Divide the distance travelled by the time taken. Question How do you calculate pace? Tap to flip Answer Divide the time taken by the distance travelled. Question What determines the units for speed? Tap to flip Answer The units for time and distance. Question Rearranging the speed formula lets you calculate which two other quantities? Tap to flip Answer Distance or time. Question What multiplier converts hours to minutes, or minutes to seconds? Tap to flip Answer 60. Question How is the density of a substance measured? Tap to flip Answer As its mass per unit of volume. Question What is the mass of a substance? Tap to flip Answer A measure of the quantity of matter in it. Question How do you calculate density? Tap to flip Answer Divide the mass by the volume. Question Rearranging the density formula lets you calculate which two other quantities? Tap to flip Answer Mass or volume. Question What determines the units for density? Tap to flip Answer The units for mass and volume. Question What is pressure? Tap to flip Answer The perpendicular force applied to an object's surface per unit area over which the force is distributed. Question What is a force? Tap to flip Answer A push or a pull on an object. Question How do you calculate pressure? Tap to flip Answer Divide the force by the area on which it acts. Question When finding the pressure a solid exerts on a floor, which area do you use? Tap to flip Answer The area in contact with the floor, not the solid's total surface area. Question Metric units are based around which standard units? Tap to flip Answer The metre, the gram and the litre. Question When was the imperial system of units created? Tap to flip Answer In the early 1800s, during the British Empire. Question How do you find the overall average speed of a journey with two parts? Tap to flip Answer Divide the total distance travelled by the total time taken. Question Can you find an overall average speed by averaging the separate average speeds? Tap to flip Answer No. Use the total distance divided by the total time. Question How many cm² are in 1 m²? Tap to flip Answer 10 000 cm². Question To convert m³ to cm³, what do you multiply by? Tap to flip Answer 100³. Question What does rate of flow measure? Tap to flip Answer The volume of fluid passing through a pipe or channel per unit of time. Question Which compound measure do average speed cameras involve? Tap to flip Answer Average speed.
