      this where I lose it. I make 8752.5 / 60 = 145.875
    
    
    Alistair,
    
    8752.5/60 does indeed equal 145.875.  The 145.875 is in decimal
    degrees.  The minutes portion would be 0.875*60 = 52.5 minutes.  So
    145.875 decimal degrees equals 145 degrees, 52.5 minutes.
    
    Jared Sherman pointed out a more convenient calculation, and Doug Royer
    a calculator method.
    
    Hope this helps,
    
    Fred
