A man wants to reach from A to the opposite corner of the square C (Figure). The sides of the square are 100m each. A central square of 50m × 50m is filled with sand.
Outside this square, he can walk at a speed 1ms^{−1}. In the central square, he can walk only at a speed of v ms^{−1}(v < 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?
