Solution
\(\textrm{Say: }\)
Let’s find out the estimated length of the duster if each piece of chalk is 2 inches.
\(\textrm{Steps: }\)
\(\bullet\) We can observe that the length of the gap between the first and the second chalk is almost half the length of each chalk.
\(\bullet\) So, the length of the gap will be half of 2 inches = 1inch
\(\bullet\) Length of 3 chalks = 2 + 2 + 2 = 6 inches
\(\bullet\) The length of the duster = Length of 3 chalks + Length of the gap between the first and the second chalks
\(\bullet\) So, the length of the duster = 6 inches + 1 inch = 7 inches
