A student is tasked with determining the density of the metal used to make ball bearings. To find the diameter, 10 identical balls are lined up with a ruler.

The positions on the scale were estimated to be: P 1.0 ± 0.2 cm, Q 20.2 ± 0.2 cm. Write down the value for the distance L using the same format.

The mark scheme is shown once you've answered.
