Question

You are doing an experiment to determine how many passengers would fit into a full-sized plane. If a scale model plane has space for 87 scaled down passengers, how many would fit into the actual plane?

Answer 1

The real place should theoretically have space for 87 passengers if it is an exact model and doesn't have modifications in the seat numbers.

Answer 2

If the "scales" for the plane model and the people models were the same, then the experiment indicates that the real plane would hold 87 real people.
