It is becoming more confusing as GPS co-ordinates usually use degrees, minutes and decimals of a minute.
In this case it can't be 52 deg, 07 min. and 62 seconds, 'cos there are only 60 secs in a min. so it must be 07.62 mins - as someone said around 37 secs if you are trying to plot on a large scale chart.
The problem is when both Lat. and Long. show values less than .60, one than has to know if one is dealing with minutes and decimals of a minute, or minutes and seconds.
Time the world kicked seconds in to touch, and just used decimals of a minute.
At the end of the day, stop trying to do a maths exam in a rattling steel cabinet, do not strive after theoretical accuracy - except in the exam of course !
