Since a clock is a circle, to go all the way around would be 360 degrees. To figure out how many degrees it moves each minute, we need to divide the number of degrees in a full circle, 360, by the number of minutes to go that same distance. There are 60 minutes in an hour, so we divide 360 degrees (degrees in a circle) by 60 minutes (to go once around the circle). That leaves us with 6 degrees/minute must be traveled to make it all the way around a clock in 60 minutes.
