The height of instrument is 71.05 m and the foresight on a turning point is 1.93 m. After the instrument has been moved forward and set-up in a new position, the backsight on the turning point is 2.92 m. Rod readings were also taken along a profile on three succeeding stations: Sta 0+000, 1.59 m; Sta 0+020, 1.92 m; Sta 0+032.75, 1.29 m. A. What is the elevation of Sta 0 + 020? B. Which station has the least elevation along the profile? C. Determine the gradient of the ground from Sta 0 + 020 to Sta 0 + 032.75 in three decimal places of %.
