60 TO 1 RULE
60/60 = 1 (1 radial per NM)
60/30 = 2 (2 radial per NM)
60/20 = 3 (3 radial per NM)
60/120 = 0.5 (.5 radial per NM)
Picture yourself standing 60 feet from a Car and point your hand 20 degrees to the right at a motorcycle. Now let's say you move to 30 feet from the car and want to point at the same motorcycle that was 20 degrees but now your arm has to move in order to point at the same motorcycle. Your arm would need to be at 40 degrees now since you moved closer to the car, hence twice the angle. So at 30 DME you are now two radials per NM. Make sense?
