There are 360 degrees in a circle, and a clock is a circle, right?  So, divide 12 by 360.  You get 1 out of 30.  If the minute hand rotates 12 degrees, it moves two minutes, since 30 times 2 = 60, and there are 60 minutes in a hour, which means that 360 degrees on a clock is 60 minutes.  Sorry, does that make sense?

a clock is a circle 360°  one revolution is 60 minutes
12° out of 360° = same fraction as the number of minutes out of 60
let the number of minutes be x
12/360 = x/60

x = 12*60/360  simplify by dividing by common factors  x = 2 minutes

start at 5:05 and 2 minutes later means 5:05 + 0:02 = ?
