You have a strip of paper that is 1.5 m (150 cm!) long. You want to mark the distance from the Sun to Alpha Centauri
Using the table below, you must choose one linear scale (e.g., “1 cm = X ly”) that allows all three stars to fit on the strip. Assume that the Sun is marked at the edge of the strip.
