Q2/ The following consecutive readings were taken with a level along a line at common interval of 50 m. the first reading was at change 0+00 where the RL 60.00. The instrument was shifted after the third and seventh reading. 3.150, 2.245, 1.125, 0.860, 3.125, 2.760, 1.835, 1.470, 1.965, 1.225, 2.390, and 3.035m. Draw the longitudinal section profile) of the leveling process if you know that the elevation of required road line is 59.80m
