Final answer:
The minimum distance required for doors swinging in a series from edge to edge is equal to the sum of their widths.
Step-by-step explanation:
When doors are swinging in a series from edge to edge, the minimum distance required between the doors is equal to the sum of their widths. This ensures that the doors do not collide when opening or closing.
For example, if each door has a width of 1 meter, and there are three doors in a series, the minimum distance required would be 3 meters (1 meter for each door).
Therefore, the minimum distance required for doors swinging in a series from edge to edge is equal to the sum of their widths.
