Cars moving in a road
Position of cars in the road after \(10\) seconds
From the given images, it is clear that the distance covered by the car from one horizontal white strip to another is measured using a scale. Suppose, the scale reading is \(2\ cm\) then, it is equivalent to .
The formula for the speed is given as
On substituting the given values in the formula, we get the speed as .
