A highway centerline subgrade elevation is $975\mathrm{.}20$ ft $.$ at station $11+00$ and elevation of $983\mathrm{.}70$ ft $.$ at station $16+00$ with a straight grade in between. To set blue tops for this portion of the centerline, a level is setup in the area and a plus sight of $4\mathrm{.}19$ ft $.$ is taken on a bench mark that has an elevation of $982\mathrm{.}70$ ft $.$ From this HI $,$ what are the rod readings that will be necessary to set blue tops for $50\text{'}$ stations from $11+00$ through $16+00?$ Calculate the station and grade first. Then calculate the difference and the rod reading for the to read for each station.
