2. Several lines of levels were run over different routes from BM1 in order to set BM2 and establish its elevation. The lengths of these routes and the value of the elevations determined are shown blow. Determine the most probable elevation of BM2. Show your final answer and your computations in the table. Any additional work may be shown below the table. Route a b C d Length (miles) 4 8 2 6 Measured Elevation (ft) 973.09 973.56 973.24 973.70
