Wouldn't the math be 60 min/360 degrees of a circle for minute hand, 12 hr / 360 degrees of a circle for hour hand? Just a thought- I don't know if that gets you closer to a solution.....

Hey all,

I am having my students work on a clock exercise from our book and am struggling on showing them the easiest to understand solution.  We have a clock with move-able min and hour hands.  We have to create functions to return the time the clock is set to.  Any easy way to get the function to return the time?  I cannot think of how to do it since the hands are 'roll'ing around the center point of the face.
