Where should the five friends meet to minimise the total walking distance?
Tim is represented by the circle marked 1
Each of the circles marked 2 represents a pair of twins.
They can only walk along the grid lines.
Choose a meeting point. Calculate the distance all five people will have to walk added together to get there. Is that the best place to meet?
