Also, the depth of $\displaystyle 9m$ is $\displaystyle 11 \ \mathrm{am}+3.6277 \ \mathrm{Hours} = 2.6277 \ \mathrm{pm}$. How did they convert that to $\displaystyle 2.38 \ \mathrm{pm}$?

Think of 2.6277 as degrees .... The 0.6277 then converts to 37 minutes and 39.72 seconds ...... (Remember that 1 hour = 60 minutes and 1 minute = 60 seconds which is why the angle analogy works).
