First you spot it in the scope.
Plot the range and AOB and make an extended course line.
Now take hydrophone bearings with 3.15 min seperation = speed (IF he continues his course...)

You are para-phrasing too much.

Useing hydrophones to "nail the speed" is not useing a
"Single periscope observation... [to] compute all the variables".
