Given,
Distance Sandy covered while walking east, s₁=10 blocks.
Distance Sandy covered while walking west, s₂=5 blocks.
The total distance covered is the sum of the two distances given in the question.
That is,
[tex]\begin{gathered} \text{distance}=s_1+s_2 \\ =10+5 \\ 15\text{ blocks} \end{gathered}[/tex]
The displacement is the shortest distance between the starting and ending point of a path.
Let us assume that the eastward direction is positive and the westward direction is negative.
Thus the total displacement of Sandy is given by,
[tex]\text{displacement}=s_1-s_2[/tex]
On substituting the known values,
[tex]\text{displacement}=10\text{-5=5 blocks.}[/tex]
Therefore total distance covered by Sandy = 15 blocks.
And the total displacement of the Sandy = 5 blocks
