The theodolite is placed in the middle of points A and B, where the subtense bar is positioned. The instrument reads 0°24’56.2” and 0°44’36.8” for A and B. Compute the distance between A and B.

11. (a) Calculate the minimum arrival times for seismic reflections from each of the reflecting interfaces in the following section. Consider the base of the lower- most bed to be a reflector as well. (b) What is the average velocity of the section for a reflection from the base of the dolomite? (c) Using the listed densities calculate the reflection coefficient for each interface (except the base of the dolomite). Which interface gives the strongest
