Using the scale (1 light-minute equals 10 mm), how many millimeters represent a light year? On this scale, what is the distance from Earth to the nearest star? To the Andromeda Galaxy? (Note that 1 meter = 103 mm and that 1 km = 103 meters.)
well, how many minutes in a year? That many * 10 mm. Or, as we like to call them, cm.
