The elevations of two stations A and B are 92.50 m, and 142 m, and the distance between them is 50 km. The mean elevation of the intervening ground may be assumed as 75 m. Determine the minimum height of the signal required at B in order that the line of sight is nowhere less than 2 m above the ground.
