Solution
If Candace walk the sideways
[tex]\begin{gathered} distance=20+40 \\ \\ distance=60 \end{gathered}[/tex]
If Candace walks through the park
[tex]\begin{gathered} distance=\sqrt{20^2+40^2} \\ \\ distance=45 \end{gathered}[/tex]
The distance or meters Candace saw when he walks through the park is
[tex]60-45=15[/tex]
Therefore, the answer is 15
