Write a formula for converting a measure of degrees in degrees, minutes, and seconds to a decimal number of degrees. The formula should convert, for example, 39º 5’ 34” to 39.093º.

The model includes the assumption that a full degree equals 60 minutes and one minute equals 60 seconds. Use the following symbols:
D = decimal number of degrees
d = whole number of degrees
m = number of minutes
s = number of seconds

A.) D = d + m(60) + s (60)
B.) D = d + m(1/60) + s (1/60)
C.) D = d + m(60) + s (3600)
D.) D = d + m(1/60) + s (1/3600)

D+1/60+1/3600
