The camera measures the speed of a vehicle on the road to determine whether
the vehicle is travelling too fast.
The camera takes two photographs of the vehicle 0.25 s apart.
The photographs are used to measure the distance travelled by the vehicle during
this time.
(i) State the formula linking average speed, distance moved and time taken.
