Write a formula for converting hours, starting with midnight as zero, to a decimal number of degrees. Assume that a full day equals 360ยบ, 60 minutes equals one hour, and 60 seconds equals one minute. Use x, y, and z to represent hours, minutes, and seconds respectively. Use T for the decimal number of degrees.

T = 360(x + y + z)

T = 60(x + y + z)

T = 15(x + y/60 + z/3600)
