We can use formulas to model real-life situations. For example, the formula for calculating speed is speed = distance ÷ time. It is possible to calculate the speed, distance or time if you have the ...

A distance-time graph shows how the distance travelled by an object changes over time and can be used to calculate the speed of the object. A sloping line on a distance-time graph shows that the ...

First of all there’s the engines speed calculated as number of revolutions per minute (revs) that influence a car’s top speed. Obviously the engine will give it’s best on this matter at his maximum ...
