Explanation:

Step1: Count the number of small - intervals

There are 5 small intervals between two consecutive big lines (e.g., between 50 and 60).

Step2: Calculate the value of each small - interval

The difference between two consecutive big lines is 10. Divide this difference by the number of small intervals. Let the value of each small - interval be $x$. We have $x=\frac{10}{5}=2$.
