The speed of moving vehicles is sometimes measured using detectors buried in the road. The two detectors are about 1 m apart. As a vehicle passes over the first detector, an electronic timer starts. As it passes over the second
detector, the timer stops.
Explain how the vehicle's speed can then be calculated.
