Okay, here we have this:

Considering the provided information, we are going to calculate the requested distance, so we obtain the following:

Then based on this we can see that we are talking about a right triangle, for which we can use the Pythagorean theorem to find the missing measure, then we have:


\begin{gathered} 40^2=24^2+x^2 \\ x^2=40^2-24^2 \\ x^2=1600-576 \\ x^2=1024 \\ x=√(1024) \\ x=32 \end{gathered}

Finally we obtain that she need to go 32 met
