$$\text{Meeting points:}$$ $$\textit{1st time: Brenda and Sally, together, run half of the circumference}$$ $$\textit{2nd time: Brenda and Sally, together, run the full circumference}$$ $$$$ $$\text{Brenda:}$$ $$\textit{1st time: Brenda runs 100m}$$ $$\textit{2nd time: Brenda runs 200m (twice as far as the 1st time)}$$ $$$$ $$\text{Sally:}$$ $$\textit{2nd time: Sally runs 150m}$$ $$$$ $$\textit{Length of the track} = {200} + {150} = {350}$$
