Question 877551
{{{D[s]=24}}}
{{{D=4+3D[w]}}}
The distance between them is the hypotenuse of a right triangle where the sides are the distance traveled south and the distance traveled west.
Use the Pythagorean theorem,
{{{D^2=D[s]^2+D[w]^2}}}
{{{(4+D[w])^2=24^2+D[w]^2}}}
{{{16+8D[w]+D[w]^2=576+D[w]^2}}}
{{{8D[w]=560}}}
{{{D[w]=70}}}
{{{D=4+3(70)}}}
{{{highlight(D=214)}}}
