add these together:
deg = 42 mins= 12 secs= 13
deg = 59 mins= 56 secs= 15
deg =257 mins= 51 secs= 35
totals:
deg =358 mins=119 secs=305
Divide seconds by 60 -> that result is added to minutes, with remainder in seconds
we get 5 minutes and 5 seconds leftover
deg =358 mins=124 secs=5
Divide minutes by 60 -> that result is added to degrees, with remainder in minutes
we get 2 degrees and 4 minutes leftover
deg =360 mins=4 secs=5
