A man wants to reach from A to the opposite corner of the square C. The sides of the square are 100 m. A central square of `50mxx50m` is filled with sand. Outside this square, he can walk at a speed 1 m/s. In the central square , he can walk only at a speed of v m/s `(v lt 1)`. What is smallest value of v for which he can reach faster via a straight path through the sand than any path in the square outside the sand ?
