Question 6
The diagram shows a city block (shaded). Peter starts from $A$ and moves to the east while Toney starts from $A$ and moves to the south. They both follow the perimeter of the city block, and eventually meet at the point $D$ on the side $BC$, 2 km from $C$. If the constant speed of the Toney is $\frac34$ of the constant speed of the Peter, what is the length of the zig-zag line from $A$ to $C$?
Give the answer in km.
