Average Speed =
Distance / Time
Time / Distance
Distance x Time
Time x Distance
Why is the speed known as average speed?
Because the speed of a car is always changing on a journey
You cannot accurately calculate the exact speed
Some factors effect the speed therefore it is known as 'average'.
Distance Travelled =
Average Speed x Time
Average Speed / Time
Is this the correct formula? =(u+v) ÷ t x 2
What does 'v' stand for in the equation?
The finishing Speed
The starting Speed
The distance travelled
The time taken
What does the gradient in a Distance-Time graph tell you?
The speed
