In order to obtain the stadia interval factor of a certain instrument, the stadia rod was held vertically at marked distances of every 25.0m. The stadia interval at each location was observed as follows: 0.251, 0.500, 0.753, and 1.237, respectively. The instrument was then setup over station A, and the corresponding hair readings on a rod held vertically at station B were 1.050, 1.900 and 2.750 with the line of sight horizontal. Calculate the horizontal distance AB.
