Homework Help: let's try this again - precal

Write a formula for converting hours, starting with midnight as zero, to a decimal number of degrees. Assume that a full day equals 360º, 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)

And yeah, this is supposed to be in military time.

I suppose you have posted three choices for the answers.

You would choose the choice which evaluates to 360° at 24:00:00 (i.e. x=24, y=0, z=0).

If more than one choice fit, then you need other tests.
